He may be microchipped... it would be a great idea to bring him in and see if you can find his owner. I'm certain that a Yorkie running around is not a stray. I'm very glad you feel kindly enough toward this pup to give him a home but he may have a family that is very broken hearted and missing him. Please at least try to find them.
As for the vomiting, he may have stomach upset because of a change in food. |
