hey agaiN! how many years is in dog years like if my dog was 1 year old would it be 7 years old or 4 years old??

It's a good question.

Contrary to popular belief, one human year does not equal seven dog years.

Dogs age quite differently depending on their size. A five year old Chihuahua is still quite young but a five year old Great Dane is entering his senior years.
