More About the Dog Year Chart

If you own a dog, you might have heard that 1 Dog Year is equal to 7 Human years. Well, calculating your dog’s age in human years isn’t that simple. During the early stages, dogs grow and mature more quickly than us. As mentioned in the above Dog Year Chart, the first year of your doggy’s life is equal to almost 15 human years.

Do All Dog Breeds Age Alike?

No, all dog breeds don’t age alike. The size and breed play a vital role. Smaller breeds tend to live longer than the larger ones, but they grow and mature more quickly in the initial few years of life. A larger breed pup might age a bit slow during the first few years, but almost nears middle age by 5. The smaller or tiny toy breeds don’t become “senior dogs” until the age of 10. The medium-sized breeds are around the middle on both parameters.
