It varies, but cats and small dogs are generally considered “senior” at seven years of age. Larger breed dogs tend to have shorter life spans compared to smaller breeds and are often considered senior when they are 5 to 6 years of age. Contrary to popular belief, dogs do not age at a rate of 7 human years for each year in dog years.
Age is not a disease. Although senior pets may develop age-related problems, good care allows them to live happy, healthy and active lives in their senior years.
