The age of a dog varies directly as it’s equivalent age in human years if a 3 year old is considered 21 what is the age of an 8year old dog in human years
1 1/7 years old. For a 3 year old dog is 21 because 1 human year is 7 dog years so if a dog is 8 in dog years it is 1 1/7 years old in dog years i believe.
