How Long Do Dogs Live; Small, Medium and Large Breeds

What is the Average Lifespan of Dogs?

A dog lives for 10 to 13 years on average but this could be affected by a number of factors. Reportedly, dogs having a healthy lifestyle and diet have successfully lived for up to 20 years, which is a lot for a dog. Dog age is different from human age and the below infographic will help you understand it.

Besides, we have explained some of the key factors that affect the life expectancy of canines.

How Long Do Dogs Live with Cancer?

Without any treatment, a dog diagnosed with cancer is expected to live anywhere between 1 to 2 months. With treatment, the life expectancy could extend up to 20 months or longer depending on the type and stage of cancer. However, no one can predict the exact life expectancy as each case is unique.

Cancer is one of the leading causes of death in dogs worldwide, affecting nearly 50% of dogs over the age of 10. But is a cancer diagnosis a death sentence for your dog? Not necessarily. The outcome depends on several critical factors including the type of cancer, stage at diagnosis, your dog's overall age and health, and the treatment options pursued.

Types of Cancer and Their Impact on Lifespan

Different cancers affect dogs in vastly different ways:

Lymphoma is one of the most common cancers in dogs. Without treatment, dogs typically survive only 4 to 6 weeks. With chemotherapy, approximately 80-90% of dogs achieve remission and can live 12 to 14 months on average, with some surviving 2 years or more. Breeds like Golden Retrievers and Boxers are at higher risk.

Osteosarcoma (bone cancer) is aggressive and primarily affects large breeds like Great Pyrenees, German Shepherds, and Rottweilers. Without treatment, survival is typically 1 to 2 months due to pain and complications. With amputation and chemotherapy, dogs can live 10 to 12 months on average.

Mast cell tumors vary significantly based on grade. Low-grade tumors may be cured with surgery alone, while high-grade tumors have a more guarded prognosis even with aggressive treatment. Breeds like Bulldogs and Boxers are predisposed.

Hemangiosarcoma is unfortunately one of the most aggressive cancers. Even with surgery and chemotherapy, average survival time is only 4 to 6 months, though some dogs exceed this. According to the American Kennel Club, this cancer commonly affects the spleen, heart, and liver.

Factors That Influence Survival Time

Early Detection: Dogs diagnosed at earlier stages consistently have better outcomes. Regular veterinary checkups and being attentive to changes in your dog's behavior, appetite, or physical condition can make a significant difference. The Veterinary Cancer Society recommends bi-annual wellness exams for dogs over 7 years old.

Overall Health: Dogs that are otherwise healthy, at a proper weight, and have strong immune systems typically respond better to treatment. Maintaining your dog's health through proper nutrition and supplements like CBD oil for dogs may support overall wellness during treatment.

Age: While cancer is more common in older dogs, younger dogs often handle treatment better and may have longer survival times post-diagnosis. Understanding how long dogs live on average helps put cancer prognosis in perspective.

Breed: Some dog breeds are genetically predisposed to certain cancers. Healthiest dog breeds with fewer genetic issues may have better outcomes when facing cancer.

Treatment Approach: The combination of surgery, chemotherapy, radiation, and newer treatments like immunotherapy can significantly extend life expectancy. Dogs receiving multimodal treatment generally live longer than those receiving single treatments.

The Financial Reality of Cancer Treatment

In many cases, the financial conditions of the owner also affect the life expectancy of a canine. Cancer treatment for dogs can range from $1,000 for basic surgery to $10,000 or more for comprehensive treatment including chemotherapy and radiation.

This creates difficult decisions for pet owners. However, palliative care options exist that focus on maintaining quality of life and managing pain without pursuing aggressive treatment. These options can help dogs live comfortably for weeks to months at a lower cost.

For emotional support animal owners, some pet insurance plans and assistance programs may help offset costs. Organizations like the Pet Fund and RedRover Relief offer financial assistance for pet medical care.

Signs of Cancer in Dogs to Watch For

Early detection improves outcomes, so watch for these warning signs:

• Lumps or bumps that grow or change
• Wounds that do not heal
• Unexplained weight loss
• Loss of appetite lasting more than a day or two
• Difficulty eating, swallowing, or breathing
• Persistent lameness or stiffness
• Difficulty urinating or defecating
• Unexplained bleeding or discharge
• Chronic vomiting or diarrhea
• Lethargy or decreased interest in activities

Some of these symptoms overlap with other conditions like hypothyroidism in dogs or yeast infections, so proper veterinary diagnosis is essential.

Making the Decision: Treatment vs. Quality of Life

When facing a cancer diagnosis, the goal should always be quality of life over quantity. Some dogs tolerate chemotherapy remarkably well with minimal side effects, while others may struggle. Working closely with your veterinarian or a veterinary oncologist helps you make informed decisions based on your dog's specific situation.

Many owners find that even a few additional months of quality time with their beloved companion is worth pursuing treatment. For those with an emotional support animal, this bond is particularly meaningful. The companionship dogs provide can be invaluable for individuals dealing with depression, anxiety, or PTSD.

If you're facing the difficult reality of losing your ESA, having time to prepare emotionally and potentially get an ESA letter for a new companion when you're ready can be part of the healing process.

Supporting Your Dog Through Cancer

Regardless of treatment decisions, there are ways to support your dog's comfort:

• Maintain a consistent routine to reduce stress
• Provide comfortable bedding and easy access to food and water
• Consider CBD dog treats for natural pain and anxiety management (consult your vet first)
• Keep up with gentle exercise as tolerated
• Spend quality time together with plenty of affection

The American Veterinary Medical Association offers additional resources for pet owners navigating cancer treatment decisions.

How Long Do Dogs Live in the Wild?

A wild dog could live for up to 12 years, but most only survive for 5 to 7 years on average. Dogs living without human care face significantly shorter lifespans compared to their domesticated counterparts, who typically live 10 to 13 years with proper care.

Wild dogs include several categories: feral domesticated dogs that have returned to living without humans, wolf-dog hybrids, dingoes, and African wild dogs. These animals often develop different physical characteristics than pet dogs, including larger canine teeth, more muscular builds, and heightened survival instincts.

Why Wild Dogs Have Shorter Lifespans

Lack of Veterinary Care: Without access to vaccinations, parasite prevention, and medical treatment, wild dogs succumb to diseases that domestic dogs easily survive. Conditions like heartworms, parvovirus, and distemper spread rapidly through wild populations. The World Organisation for Animal Health estimates that preventable diseases account for nearly 40% of wild dog deaths.

Nutritional Deficiencies: Wild dogs must hunt or scavenge for every meal. Inconsistent food sources lead to malnutrition, weakened immune systems, and stunted growth. Unlike domestic dogs who receive balanced diets formulated for their needs, wild dogs often go days without adequate nutrition.

Predators and Territorial Conflicts: Wild dogs face threats from larger predators including wolves, coyotes, mountain lions, and even other dog packs. Territorial disputes result in fatal injuries, and without medical intervention, even minor wounds can become life-threatening infections.

Environmental Hazards: Exposure to extreme weather, vehicle collisions, poisoning from contaminated food sources, and human persecution all contribute to shortened lifespans. According to the Humane Society International, millions of stray and feral dogs die annually from environmental factors alone.

Parasites and Disease: Without flea treatments, deworming, or regular grooming, wild dogs suffer from severe parasite infestations. Mange, tick-borne diseases, and intestinal worms drain their health and energy reserves needed for survival.

Types of Wild Dogs and Their Lifespans

Feral Domestic Dogs: These are pets or descendants of pets living without human care. They typically survive 3 to 5 years in urban environments and up to 7 years in rural areas with less traffic and more food sources.

Dingoes: Australia's wild dogs can live 7 to 10 years in the wild and up to 15 years in captivity. They are more adapted to wild living than feral domestic dogs, having evolved over thousands of years. The Australian Museum documents their unique adaptations for survival.

African Wild Dogs: These endangered pack hunters live 10 to 12 years in the wild when conditions are favorable. Their highly social structure and cooperative hunting give them survival advantages over solitary wild dogs.

Wolf-Dog Hybrids: Lifespan varies greatly depending on the percentage of wolf genetics and environment, ranging from 5 to 14 years. These hybrids often struggle in both wild and domestic settings due to unpredictable behavior.

Feral Dogs vs. Stray Dogs

It's important to distinguish between feral and stray dogs:

Stray dogs were once pets and retain some socialization with humans. They may approach people for food and can often be rehabilitated into domestic life. Many strays can be rescued and potentially become wonderful emotional support animals with proper care and training.

Feral dogs have had little to no human contact or have been wild for so long they've lost domesticated behaviors. They actively avoid humans and are extremely difficult to rehabilitate. These dogs typically form packs with hierarchical social structures similar to wolves.

The Domestic Advantage

The stark difference in lifespan between wild and domestic dogs highlights the value of human care. Domestic dogs benefit from:

• Regular veterinary checkups and preventive care
• Consistent nutrition and clean water
• Protection from predators and environmental hazards
• Treatment for injuries and illnesses
• Shelter from extreme weather
• Mental stimulation and companionship

Breeds that might struggle in the wild, like small dogs and teacup breeds, thrive in domestic environments where their size isn't a survival disadvantage. Conversely, guard dog breeds like Anatolian Shepherds and Kangal Shepherd Dogs retain more survival instincts but still live significantly longer with human care.

Can Wild Dogs Be Domesticated?

Young feral puppies under 4 months old can often be successfully socialized and domesticated. Adult feral dogs rarely fully adapt to domestic life due to deeply ingrained survival behaviors and fear of humans.

If you're considering adopting a former stray, patience and proper training are essential. Many rescued strays become incredibly loyal companions, grateful for the security of a loving home. Some owners even qualify them as emotional support animals learn how to qualify for an ESA if you're considering this option.

Global Wild Dog Populations

Wild and feral dog populations present challenges worldwide:

• An estimated 200-300 million stray dogs exist globally
• India has the largest stray dog population at approximately 35 million
• Feral dog packs can threaten livestock, wildlife, and occasionally humans
• Many countries implement trap-neuter-return programs to humanely manage populations

The International Companion Animal Management Coalition works globally to address stray dog populations through humane methods rather than culling.

How Long do Dogs Live with Diabetes?

On average, 50% of diabetic dogs survive to live for 2 to 3 months without any treatment. With treatment, these dogs are expected to live for as long as their non-diabetic counterparts and may have a natural ‘non-diabetic’ death.

How Long do Dogs Live with Congestive Heart Failure?

Congestive heart failure is a genetic disease that could occur at any time of the dog’s life. However, once it has been diagnosed, the dog is expected to live for 6 to 12 months. There are 2 types of CHF; right-sided congestive heart failure (RS-CHF) and left-sided congestive heart failure (LS-CHF) and the life expectancy in both cases remains the same.

How Long Do Dogs Live with Kidney Failure?

With timely diagnosis and treatment, dogs with kidney failure can live many healthy months to several years depending on the stage at diagnosis and how well they respond to treatment. However, kidney disease is often called a "silent killer" because by the time symptoms appear, nearly two-thirds of kidney function has already been lost and may be beyond repair.

The prognosis varies dramatically based on whether the dog has acute kidney failure (sudden onset) or chronic kidney disease (gradual deterioration). Understanding the differences and stages can help you make informed decisions about your dog's care.

Acute vs. Chronic Kidney Failure

Acute Kidney Failure (AKF) occurs suddenly, often within days or hours. Common causes include:

• Toxin ingestion (antifreeze, grapes, raisins, certain medications)
• Severe dehydration
• Heatstroke
• Infections like leptospirosis
• Urinary blockages

If caught immediately and treated aggressively, dogs with acute kidney failure can sometimes recover full or partial kidney function. According to the Merck Veterinary Manual, approximately 50-60% of dogs with AKF survive if treatment begins within 24 hours. Without treatment, acute kidney failure is often fatal within days.

Chronic Kidney Disease (CKD) develops gradually over months or years and is irreversible. It's most common in senior dogs, with the International Renal Interest Society estimating that 1 in 10 dogs will develop CKD in their lifetime. While the damage cannot be undone, proper management can significantly slow progression and maintain quality of life.

Stages of Chronic Kidney Disease and Life Expectancy

The International Renal Interest Society (IRIS) classifies CKD into four stages based on creatinine levels and other markers:

Stage 1 (Mild): Kidney damage is present but function remains relatively normal. Dogs at this stage may show no symptoms and can live 4+ years with proper management. Many dogs are diagnosed incidentally during routine bloodwork.

Stage 2 (Mild to Moderate): Kidneys are functioning at 33-66% capacity. Dogs may show increased thirst and urination. With dietary management and monitoring, dogs typically live 2 to 4 years.

Stage 3 (Moderate to Severe): Kidneys are functioning at 15-33% capacity. Symptoms become more apparent including weight loss, decreased appetite, and lethargy. Average life expectancy is 1 to 2 years with treatment, though some dogs exceed this.

Stage 4 (Severe/End-Stage): Kidneys are functioning below 15% capacity. Dogs experience significant symptoms including vomiting, weakness, and toxin buildup. Life expectancy at this stage is typically weeks to months, though some dogs stabilize with intensive management.

Symptoms of Kidney Failure in Dogs

Early detection dramatically improves outcomes. Watch for these warning signs:

• Increased thirst and urination (often the first sign)
• Decreased appetite and weight loss
• Vomiting and nausea
• Lethargy and weakness
• Bad breath with ammonia-like odor
• Pale gums
• Mouth ulcers
• Blood in urine
• Poor coat condition
• Muscle wasting

Some symptoms overlap with other conditions like diabetes or thyroid issues, making veterinary diagnosis essential.

Breeds Prone to Kidney Disease

Certain breeds have genetic predispositions to kidney problems:

• Cocker Spaniels - prone to familial nephropathy
• Bull Terriers - hereditary nephritis
• German Shepherds - renal cystadenocarcinoma
• Samoyeds - hereditary glomerulopathy
• Shih Tzus - renal dysplasia
• Bernese Mountain Dogs - glomerulonephritis

If you own a predisposed breed, regular kidney function screening after age 7 can catch problems early when intervention is most effective.

Treatment Options That Extend Life

Dietary Management: Prescription kidney diets are lower in phosphorus and protein while providing high-quality, easily digestible nutrients. The American College of Veterinary Internal Medicine reports that dietary therapy alone can extend survival time by 2-3 times compared to regular food.

Fluid Therapy: Subcutaneous fluids administered at home help flush toxins and maintain hydration. Many owners learn to give fluids easily, and most dogs tolerate it well.

Phosphorus Binders: These medications reduce phosphorus absorption from food, slowing disease progression and improving how dogs feel.

Anti-Nausea Medications: Controlling nausea improves appetite and quality of life significantly.

Blood Pressure Management: Kidney disease often causes hypertension, which further damages the kidneys. Medications to control blood pressure protect remaining kidney function.

Potassium Supplementation: CKD often causes potassium loss, leading to muscle weakness that supplementation can correct.

Erythropoietin: For dogs with severe anemia from kidney disease, this hormone stimulates red blood cell production.

The Role of Regular Checkups

Since kidney disease is often asymptomatic in early stages, regular veterinary checkups are crucial. The American Animal Hospital Association recommends:

• Annual bloodwork for dogs over 7 years
• Bi-annual bloodwork for dogs over 10 years
• More frequent monitoring for predisposed breeds

Early detection at Stage 1 or 2 gives your dog the best chance at a longer, comfortable life. Simple blood and urine tests can reveal kidney problems before symptoms appear.

Quality of Life Considerations

Living with kidney disease requires ongoing management, but many dogs maintain excellent quality of life for extended periods. Signs your dog is doing well include:

• Good appetite (even if modified diet)
• Interest in activities and family
• Stable weight
• Normal energy for their age
• Comfortable and pain-free

When quality of life declines despite treatment—persistent vomiting, refusal to eat, extreme weakness, or obvious discomfort—it may be time to discuss humane options with your veterinarian.

Supporting Your Dog Through Kidney Disease

Beyond medical treatment, you can support your dog's wellbeing:

• Provide fresh water at all times in multiple locations
• Feed small, frequent meals rather than large portions
• Maintain a calm, stress-free environment
• Keep up with gentle exercise as tolerated
• Monitor weight and symptoms daily
• Follow medication schedules strictly

For emotional support animal owners, managing a chronic condition can be emotionally challenging. The bond between an ESA and their owner runs deep, and watching your companion face health struggles is difficult. Consider connecting with support groups for pet owners dealing with chronic illness—the Association for Pet Loss and Bereavement offers resources for those navigating these challenges.

Preventing Kidney Disease

While not all kidney disease is preventable, you can reduce risk:

• Keep toxins like antifreeze, grapes, and certain medications out of reach
• Ensure constant access to fresh water
• Feed high-quality dog food appropriate for your dog's life stage
• Maintain regular veterinary checkups
• Address dental disease promptly (bacteria can damage kidneys)
• Vaccinate against leptospirosis if your dog has exposure risk
• Avoid unnecessary NSAID use

The Pet Poison Helpline provides 24/7 guidance if you suspect your dog has ingested something toxic—quick action can prevent acute kidney failure.

Dementia itself does not directly shorten your dog's life expectancy. In fact, studies suggest that dogs diagnosed with canine cognitive dysfunction (CCD) may actually live slightly longer than dogs without the condition. This seemingly paradoxical finding is largely attributed to the increased veterinary attention, improved nutrition, and higher-quality care these dogs receive following diagnosis.

However, while dementia may not reduce lifespan, it significantly impacts quality of life for both dogs and their owners. Understanding the progression, symptoms, and management options helps you provide the best possible care for your aging companion.

What Is Canine Cognitive Dysfunction?

Canine cognitive dysfunction syndrome (CCD or CDS) is the dog equivalent of Alzheimer's disease in humans. It's a neurodegenerative condition caused by physical and chemical changes in the brain, including:

• Beta-amyloid plaque buildup (similar to Alzheimer's)
• Decreased dopamine production
• Reduced blood flow to the brain
• Death of neurons and brain shrinkage

According to research published in the Journal of Veterinary Internal Medicine, approximately 28% of dogs aged 11-12 years show at least one sign of cognitive impairment, increasing to 68% of dogs aged 15-16 years. The Veterinary Information Network estimates that CCD is significantly underdiagnosed, with many owners attributing symptoms to "normal aging."

Stages of Canine Dementia and Progression

Dementia in dogs progresses gradually, typically over 18-24 months, though some dogs decline faster while others remain stable for years.

Mild Stage (Early): Subtle changes that owners often miss or dismiss. Dogs may occasionally seem confused, have minor sleep disturbances, or show slightly decreased interest in play. Life expectancy at this stage: 2-4+ years.

Moderate Stage: More noticeable symptoms including getting stuck in corners, forgetting commands, altered interactions with family members, and disrupted sleep-wake cycles. Dogs typically remain at this stage for 1-2 years with proper management.

Severe Stage: Significant disorientation, failure to recognize family members, loss of house training, severe anxiety, and dramatic personality changes. This stage can last months to over a year, though quality of life becomes the primary concern.

Recognizing the Signs: DISHA Symptoms

Veterinarians use the acronym DISHA to identify dementia symptoms:

D - Disorientation

• Getting lost in familiar places
• Staring at walls or into space
• Getting stuck behind furniture or in corners
• Failing to recognize familiar people or pets
• Going to the wrong side of doors

I - Interaction Changes

• Decreased interest in petting or attention
• Withdrawal from family activities
• Failure to greet family members
• Increased clinginess or neediness
• Irritability or aggression (uncharacteristic)

S - Sleep-Wake Cycle Disturbances

• Sleeping more during the day
• Restlessness and pacing at night
• Barking or whining at night for no apparent reason
• Reversal of normal sleep patterns

H - House Soiling

• Accidents indoors despite years of house training
• Forgetting to signal need to go outside
• Eliminating in unusual locations
• Not realizing they've had an accident

A - Activity Changes

• Decreased interest in play or walks
• Repetitive behaviors (pacing, circling)
• Aimless wandering
• Reduced response to commands
• Staring blankly

These symptoms can overlap with other conditions like hypothyroidism, brain tumors, or pain-related behavioral changes, making veterinary evaluation essential for accurate diagnosis.

Why Dementia Dogs May Live Longer

The counterintuitive finding that dogs with dementia often outlive their peers without the condition can be explained by several factors:

Increased Veterinary Care: Dogs diagnosed with CCD receive more frequent checkups, leading to earlier detection and treatment of other health issues.

Dietary Improvements: Many dementia dogs are switched to prescription brain-health diets rich in antioxidants, omega fatty acids, and medium-chain triglycerides (MCTs).

Supplement Regimens: Owners often add brain-supporting supplements that benefit overall health.

Environmental Enrichment: Mental stimulation efforts to slow cognitive decline also improve general wellbeing.

Closer Monitoring: Owners paying attention to cognitive symptoms notice other health changes sooner.

Treatment Options for Canine Dementia

While dementia cannot be cured or reversed, several interventions can slow progression and improve quality of life:

Medication:

• Selegiline (Anipryl) - the only FDA-approved medication for canine CCD, increases dopamine levels in the brain
• Anti-anxiety medications for dogs with significant anxiety or sleep disturbances

Dietary Management: Prescription diets formulated for cognitive health include:

• Hill's b/d (Brain Diet)
• Purina Pro Plan Bright Mind
• Royal Canin Mature Consult

These diets contain antioxidants, omega-3 fatty acids, and MCTs shown to support brain function.

Supplements:

• SAMe (S-adenosylmethionine) - supports brain cell membrane health
• Omega-3 fatty acids (DHA and EPA) - reduce brain inflammation
• Vitamin E and C - antioxidant protection
• Medium-chain triglycerides (MCT oil or coconut oil)
• Phosphatidylserine - supports neuron function

Some owners also explore CBD oil for its potential calming effects, though research specifically for canine dementia is limited.

Environmental Management:

• Maintain consistent daily routines
• Keep furniture in the same locations
• Use night lights to reduce disorientation
• Block access to stairs and dangerous areas
• Provide easy access to food, water, and outdoor areas

Mental Stimulation:

• Puzzle toys and games appropriate for their ability level
• Short, gentle training sessions
• Sniff walks rather than distance walks
• Snuffle mats for mental engagement during meals

Breeds More Susceptible to Dementia

While any senior dog can develop CCD, certain breeds show higher incidence:

• Yorkshire Terriers
• Cocker Spaniels
• Dachshunds
• Poodles
• Beagles
• Australian Shepherds

Interestingly, small dog breeds that typically have longer lifespans are more likely to develop dementia simply because they live long enough for the condition to manifest.

Managing Night-Time Disturbances

One of the most challenging aspects of canine dementia is disrupted sleep cycles. Dogs may pace, vocalize, or seem distressed at night. Strategies to help include:

• Increase daytime activity and mental stimulation
• Establish a calming bedtime routine
• Use pheromone diffusers like Adaptil
• Provide a comfortable, warm sleeping area
• Consider melatonin supplements (with vet approval)
• Use white noise to mask sounds that may trigger anxiety
• Keep a dim night light to reduce disorientation

The American College of Veterinary Behaviorists recommends consulting a veterinary behaviorist for severe cases that don't respond to standard interventions.

The Emotional Impact on Owners

Caring for a dog with dementia is emotionally demanding. Watching your once-vibrant companion become confused and anxious is heartbreaking. Many owners experience:

• Grief over the gradual loss of their dog's personality
• Exhaustion from disrupted sleep
• Guilt when feeling frustrated
• Isolation from reduced ability to travel or socialize
• Anticipatory grief as they watch decline

For emotional support animal owners, this is particularly challenging since the dog who once provided comfort now needs comfort themselves. If your ESA develops dementia, it's important to address your own mental health needs—conditions like anxiety and depression can worsen when your support system changes.

Consider whether a second companion animal might help. Understanding how many ESAs you can have and exploring options for additional support through an ESA letter can be part of your coping strategy.

Quality of Life Assessment

Since dementia doesn't directly shorten life, the decision about end-of-life care focuses on quality rather than quantity. Consider:

Good Days vs. Bad Days: Track daily quality to identify trends. When bad days consistently outnumber good days, it may be time for difficult conversations.

The Five Freedoms:

1. Freedom from hunger and thirst - Can they eat and drink adequately?
2. Freedom from discomfort - Are they comfortable physically?
3. Freedom from pain - Is pain well-managed?
4. Freedom to express normal behavior - Can they still enjoy any activities?
5. Freedom from fear and distress - Is anxiety manageable?

Joy and Engagement: Does your dog still experience moments of happiness? Do they recognize you sometimes? Do they enjoy meals, gentle pets, or any activities?

The HHHHHMM Quality of Life Scale developed by Dr. Alice Villalobos provides a framework for evaluating hurt, hunger, hydration, hygiene, happiness, mobility, and more good days than bad.

When Dementia Requires Difficult Decisions

While dementia itself isn't fatal, severe cases may warrant considering humane euthanasia when:

• Anxiety and distress cannot be adequately managed
• The dog no longer recognizes family members and seems perpetually frightened
• They cannot eat, drink, or maintain basic functions
• Sleep deprivation severely impacts their (and your) health
• There are no more moments of contentment or connection

These decisions are deeply personal. The Association for Pet Loss and Bereavement and your veterinarian can provide guidance and support during this difficult time.

How Long do Dogs Live with Lymphoma?

Without any treatment, the life expectancy of a dog could be no longer than 2 months. However, with rigorous treatment, more than 80% of the dogs go into remission with an average life expectancy of 12 to 14 months.

How Long do Dogs Live with Heartworms?

Heartworms is a serious disease for dogs but this does not mean that once diagnosed with it then your dog will not live for long. Usually, dogs with heartworms could live for up to 7 years. However, this also depends on the quality of the treatment that your dog is getting.

What Factors Contribute to a Dog’s Lifespan?

Though on average a dog lives for 10 to 13 years, there are some key factors that may play a role in increasing or decreasing some years into or from your canine’s life.

These factors include the health, weight, and lifestyle of your dog. Other factors that contribute to a dog’s life expectancy are described and discussed below.

Size of your Dog

As per some notable research, small dogs tend to live longer than large dog breeds. The University of Gottingen in Germany examined up to 70 dogs to see how weight and height influence their lifespan.

According to their results, the dogs that weigh less or are small in size live longer than the larger ones. Moreover, larger breeds also age faster and develop heart diseases.

Breed of the Dog

Many people do not believe it but the breed of your dog plays a vital role in deciding how many years your dog would keep you company. Talking about genes, purebred dogs are found to be more prone to genetic mutations and health problems. Since the breeding is very selective and it is done with less variation.

Comparatively, healthiest dog breeds, mixed breeds or mutts tend to live longer. It is mainly because these combined canines have stronger immune systems. They face fewer health issues and on average, they live 1.2 years longer than the purebred dog breeds.

Dietary Habits of your Dog

Diet plays an important role in defining the life expectancy of your canine. Therefore, providing a high quality and balanced diet to your canine will help in adding a few years to their lives.

Other than this, good quality and balanced food and healthy eating habits will keep obesity at bay and delay the aging process effectively. This is why it is important to keep track of the treats that you give to your beloved canine and keep them to a minimal level.

Ample and Suitable Daily Care

A healthy lifestyle is important if you need to add a<
