Just rescued a 13 week old retriever mix. He has eaten natural balance puppy food since he was born and I continued to feed him natural balance once rescued. Today, he went to my parents house and got into their dogs bowl of beneful dog food.
When he got home he threw up two or three times and since then has not gagged or anything but he is very tired and seems weak. I tried getting him to eat rice or drink water to rehydrate but he just won’t.
He has all his shots and saw a vet 6 days ago and was completely healthy. Is this something that will blow over or is it something to be concerned about?
I’m just worried about him rehydrating more than anything.
