If you had cheese on top, he may not even get diarrhea from it! I dont think you have a thing to worry about......I honestly do not think he even got enough meat to do him any harm.....depending on how much onion was on there, he may get an upset stomach from that....but quite honestly, I dont evewr remember hearing about onion being toxic and I used to share onion rings with mine and it never hurt them....they didnt get an entire order, but they got probably more than your pup got off 2 slices of pizza..... |
