Scientists are not entirely sure why this occurs, although there is speculation that larger dogs develop age-related diseases sooner than smaller dogs. This could be because the larger breeds grow from puppies to adults at an accelerated rate, which may increase the likelihood of abnormal cell growth and death from cancer. Regardless of the reasons behind why some dogs live longer than others, there are similar characteristics among small, medium, and large dog breeds that help determine the longevity of each group.
The average lifespan for small dog breeds ranges from 10 to 15 years, with some breeds living as long as 18 years. In general, small dogs live longer than their larger counterparts, with the shortest living breeds still exceeding the average lifespan of most large breeds. This makes them a good choice for owners who want a long-lived companion.
While variability among breeders and statistical evidence makes it difficult to determine an exact age range for any breed of dog, here are the average lifespans of the longest-lived small dog breeds and the shortest-lived breeds.
Medium-sized dog breeds range from smaller companion breeds such as French Bulldogs , to larger, active working breeds such as Border Collies and Australian Shepherd s. The average lifespan for medium-sized dog breeds is 10 to 13 years, with some breeds living even longer. As with small dogs, exact age ranges for medium-sized dog breeds are hard to determine, but there are general lifespan guidelines for each breed.
The average lifespan for large dog breeds is 8 to 12 years. Bernards , and Mastiffs. In general, giant breeds tend to live an average of 8 to 10 years, whereas large dog breeds live 10 to 12 years. Unfortunately, some dogs are predisposed to certain illnesses, just like humans. When selecting a puppy, make sure you choose a responsible breeder who fulfills the health test requirements for their breed.
In an ideal world, all dogs would live out their expected lifespans happily and healthily. Unfortunately, this is not always the case. Cancer is the leading cause of death in large dog breeds across the board. The exceedingly high rate of cancer in Golden Retrievers has led to the largest study of cancer in dogs of its kind. Researchers hope that the study will reveal information about why so many Golden Retrievers suffer from cancer and also about how the factors that contribute to cancer in dogs could also help our understanding of cancer in humans.
These health and wellbeing issues can significantly impact how long they live. Being careful about what you feed your dog could go a long way to keeping them in good shape and enabling them to be around for many years to come. For each breed, the lifespan dogs whose owners reported them to be overweight and those in optimal body condition was compared.
As the largest general-veterinary practice in the world, Banfield has more than 1, hospitals across the United States and Puerto Rico comprised of veterinary teams who are committed to providing high-quality veterinary care for more than three million pets annually.
The data extracted for this study included demographic breed, sex, neuter status and date of birth and geographic latitude and longitude of the owner's postcode variables, plus data collected during in-clinic visits date of visit, bodyweight and if available body condition , and date of death.
Pedigree status and date of birth are both owner-reported parameters and were not verified by veterinary staff.
