Hi, my 10 week old puppy ate a small piece of a hot dog and now he's not feeling well. I didn't give it to him, I know not to do that. Does anyone know what I can do for him? Thanks

He may have indigestion, I know I get it sometimes from hotdogs and it sucks. Has he been going pee and poo still? Any changes other then just looking like he feels bad? Lethargic, won't eat, etc...
