when is a dog considered senior

Pets age much faster than we do. The life span of a dog depends on its size or breed. In general, the larger the breed or size of the dog, the shorter the life span. For example, in a study of lifespans, only 13% of giant breed dogs lived to be over 10 years old. Conversely, 38% of small breed dogs live to be over 10 years of age.

Dogs are considered senior in the last 25% of their lives. Below is a list of the most common breeds with their life expectancies and age at which they are considered “senior”.

When your dog is senior, make sure they have a senior check-up with your veterinarian.

1 thought on “When is a Dog Considered Senior?

  1. Strangely, we had three hard luck strays who lived 16, 16, and 17 years old. All three weighed over 60 lbs. Maybe their starving, abused puppyhood added to their life span. No matter what, it’s always way too soon for me. It’s always like losing a loving and loved child.
