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.
In fact, feline aging is much more rapid during the first two years of life. A cat reaches the approximate human age of 15 during its first year, then 24 at age 2. Each year thereafter, it ages approximately four âcat yearsâ for every calendar year.
