Your dog is only as old as he feels, right? Well, it's a bit more complicated than that.
Smaller dogs can have longer lifespans than the giant breeds, but may suffer from more dental problems that can slow them down.
Certain breeds defy this chart with exceptionally healthy gene pools that ensure a longer, healthier life. Some overbred breeds can suffer from congenital defects that bring their lifespan down dramatically as compared to other breeds.
Be sure to get yearly checkups with your vet! As you can see, big changes can happen to a dog in just a year. Your vet will give the best advice for supplements and treatments to ensure your dog feels like a pup well into his golden years!
