16y2
Step-by-step explanation:
I’ve heard that dog years go by 7s, but another article I read said it can go by 15s. Not sure which one is correct, but if your dog is 3 in human years it would be 21 in dog years (by 7s)
I’m so sorry but I really don’t know
There are 7 more tan puppies. ( Just subtract 15 and 8 )
