When you look at the current research on spaying and neutering, the AGE at which it's done turns out to be vitally important to your dog's future health. For example, your female dog should NOT be spayed at 6 months old.
Life Expectancy of Dogs and Cats. We hope our pets will be a part of our lives for many, many years but the fact is that the average life expectancy is 10-12 years for dogs and 10-14 years for cats. Older pets have very specific needs and are particularly susceptible in later years to cancer, arthritis, and dental disease.
The formula for calculating a catâs age is a little different. Hereâs a chart to show how itâs calculated: Cats live an average of around 15 years (indoors) and 10 years or less (outdoors). Their first year is a little more maturing than dogs, but they catch up at year two. Looking over these charts has me thinking about my own pets.
