The research also highlights the most common health issues faced by older dogs, emphasizing the importance of early detection and care. The study is in the Journal of Small Animal Practice.

By analyzing veterinary electronic health records (EHRs), researchers discovered that dogs are typically described as old age at 12.5 years, though this milestone varies by breed. Smaller breeds, like Jack Russell Terriers, tend to age more slowly, with old age beginning closer to 14 years.
