I'm bad and feed Jack bits of human food (along with his regular food) - the one thing he cannot tolerate is pizza - the crust is okay, but he got some of the spices once - not sure if it was garlic or what and he vomited. No runny stools though. Jack eats cheese too, so I hope that's not bad for him...
Each dog is different though, some have more sensitive stomachs than others. Just keep an eye on him and if he vomits too much or has diarrhea, take him in as these little ones can dehydrate really quick. Good luck to you.
