The short answer to this question is, in my experience of over 21 years, most live 12 to 14 years. Smaller dogs usually live longer than bigger dogs. Most of my longest-living Hearty K9s have been first-generation F1s, Mini Poodle X Golden Retriever. But in saying that, I recently heard of one of our F1 100 lb Goldendoodles reaching over 16 years old and another large F1B passing at 15+ years.  The oldest known Hearty K9 Goldendoodle to date is Peter the Great (Sally/Jag Dec 2005)  passed at 18 years and 3 months old. (F1 Mini Goldendoodle).

Potential Reasons Why Some Goldendoodles Live Longer Than Others

How Diet Impacts How Long Goldendoodles Live

A balanced, high-quality diet and appropriate exercise influence your dog’s potential for a longer, healthier life. “Obesity in dogs can lead to a whole slew of health problems and shorten their lives, such as cancer and cardiovascular disease. A good rule of thumb is to feed your Goldendoodle[AT1]  at specific times of the day instead of leaving food out continually. Typically, your Goldendoodle will eat 1 to 4 cups a day (depending on size and life stage) that you can divide into two feedings. That way, you can monitor precisely how much your Goldendoodle is eating to ensure proper weight management. If ever in doubt on how much to feed for optimal nutrition, consult with your veterinarian.

Please understand that very high-protein diets are intended for highly active dogs; otherwise, they may lead to obesity and kidney and liver issues, similar to how cat food can be too high in protein for dogs.

Quality dog food that is size and age-appropriate should contain the nutrition your dog needs.  Some add supplements like glucosamine for larger dogs and collagen for dogs of any size have been shown to help prolong and enhance their quality of life.  (Ask me about the liquid collagen I used on 2 of my senior dogs).

The Role of Exercise in a Goldendoodle’s Lifespan

A Goldendoodle’s exercise routine should include at least 30 minutes a day, but ideally 1 to 2 hours, depending on the individual dog.  Be careful on how much exercise they get when pups are still growing, as it can be hard on the joints. See FAQ on our website under Hip Dysplasia.

Why Dental Health Is Key to Your Goldendoodle’s Lifespan

Brushing your dog’s teeth two to three times a week will also contribute to their well-being and overall health.  Yes, dogs can suffer from gingivitis and periodontal disease, which can lead to various other health problems. Regular brushing, using an ultrasonic device to eliminate plaque, or having your vet sedate and clean your dog’s teeth are different approaches to managing dental health. Also, when dogs are allowed to chew dental sticks, bully sticks, or Nylabones, it helps most dogs to keep their teeth cleaner. (Many vets do not recommend raw bones).

External Factors That Impact How Long Goldendoodles Live

Awareness of environmental hazards, some of which can be controlled and others that are much harder to manage- for example, the cleaning products you use or your neighborhood’s choice in weed or pest control- can influence the longevity and health of your Goldendoodle.  Know the plants and trees that are dangerous to a dog’s health, and ensure they don’t have access to them, especially during the puppy stages.

Cancer’s Impact on a Goldendoodle’s Life

The leading cause of death for Goldendoodles is cancer in all ages. This brings the average life expectancy down considerably.  We cannot genetically test dogs to determine whether this gene will be passed along at this time. However, cancer is often a mystery.  We desperately want to know but often do not understand why only one dog in a litter gets cancer while others do not. We all want what is best for our beloved Goldendoodles, but life is not always black and white to know what to do to help.  In humans and our beloved furry friends, cancer is devastating to our life plans with them.  

Why Choose Hearty K9s?

Carefully and ethically bred Goldendoodles tend to have fewer health issues. At Hearty K9s, we conduct health, hip, eye, and genetic testing with our breeding dogs. This is not to say that none of our puppies have ever developed health problems. Still, in discussions with my senior, now semi-retired vet, the number of issues I encounter with my puppies is very low compared to the many breeders she has worked with. 

One of my favourite emails I received was from a veterinarian caring for two senior Hearty K9s dogs that were 16 and 17 years old at the time.  She wanted to thank me for producing such wonderfully tempered and healthy dogs that were a privilege to care for. 

Many factors determine how long a Goldendoodle will live.  At Hearty K9s, we strive to provide them a healthy start with health-tested parents. By keeping up with regular vet visits and recommended vaccinations, providing a safe environment, quality nutrition, exercise, and good dental hygiene throughout their lives, you too are doing your part. If health issues do arise, we appreciate when folks inform us. If you are interested in welcoming a healthy, well-tempered Goldendoodle into your family, reach out to us today.
