When does my pet become senior? The short answer is it really depends.
Cats are generally considered senior after 10 years of age. Dogs on the other hand don’t have a “universal age of seniority” because their breeds differ so much in size. Dogs are believed by experts to have reached their senior status when they reach the last 25 percent of their breeds lifespan. Take a look at this helpful data from the American Kennel Club.
