A dog's lifespan can vary significantly with breed and size. Other factors like genetics and health conditions also play a role in how long dogs live.
The average lifespan for dogs is between 10-13 years. However, smaller dog breeds usually live longer than larger ones due to various health factors.
Small-breed dogs tend to live 10-15 years. They are prone to liver, kidney, and adrenal disease, as well as degenerative heart disease as they age.
Medium-size dogs align with the overall average dog lifespan of 10-13 years. Lifespans and diseases of concern vary from breed to breed.
Large-breed dogs have a slightly shorter lifespan, at 9-12 years. They are more likely to be affected by arthritis and certain types of cancer.
Giant-breed dogs have the shortest average lifespan, at 8-10 years. They are more prone to bone cancers and neurologic diseases than smaller dogs.
To help your dog live longer, select a responsible breeder, follow your vet's guidance, and maintain a healthy weight for your dog.
