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.
