I have a 10 month old dog who likes to chew on everything and he has been throwing up/ having blood in his poop. He is doing that either from chewing on tree bark "I don't know if he walled any" or eating some noodles that had a bit of spice to it. And he ate an played a little yesterday and didn't vomitt or have any more blood in his poop but I was wondering if he does again if I can give him a bit of my six year old brother's theraflu to him in his dog food.
