Focus on our Senior Pets


In today’s world, dogs and cats are living longer, healthier lives than ever before.  In Canada, there is an estimated 7 million geriatric pets.  As our pets get older, they require special attention and care.  We need to work with our clients to help with their quality of life as the pets’ age.


Defining “Senior”:

Cats:   from ages 7-10 are considered “mature”, ages 11-14 are “senior” and over 15 are “geriatric”

Dogs:  from 7 and over are considered “senior”, however with dogs, breed type plays a part in determining “senior”.  Small breeds are not considered senior until ages 10-13, while large and giant breeds age faster and can exhibit age related changes earlier.
