Hi, I am wondering if anyone can help me... my brother fed his 7 week old puppy a tbsp of yogurt a couple of hours ago,and she has been acting lethargic, hot and breathing heavy. He is currently at the Vet with her right now, but I am just wondering if you should even be giving a puppy yogurt or not (his vet told him to give her some so that she would grow faster). Thank you to anyone who can answer my question.
