* Dog years are a simplified concept. Dogs age much faster in their early years, but their aging slows down as they get older. There isn't a direct, linear conversion like 1 human year = 7 dog years.
* Breed matters. Smaller dogs tend to live longer than larger dogs, and their aging rates can be different.
General Estimates:
* First Year: 15 dog years
* Second Year: 9 dog years
* After 2 Years: Roughly 4-5 dog years per human year
Using this, a 14-year-old human would be roughly equivalent to a 70-75 year old dog.
Important: These are just estimates. It's always best to talk to your veterinarian for personalized advice on your dog's health and aging.
