My puppy is pretty big for a Yorkie, but don't worry because he hasn't gained any weight in the last 2 months and he is 5 months old too! My vet said that they are 85% done growing by the time they are 6 months, so unless your puppy is going to almost double in size in the next month, I doubt he will be 15 lbs. I think some dogs get their growth spurt earlier than others so he may not grow much more. |
