Do you feed him table scraps? When my girl was younger we let her lick a plate of something that had onions in it and she got really sick over it. If you already know what you can't feed a dog then disregard this but, onions, garlic, raisins, and chocolate are really hard and toxic for them to eat. There are other things they can't handle but I thought that's my best guess as far as the diarhea and vomiting go. Good Luck. |
