My dog just threw up the back end of a MOUSE OR RAT!! I just saw the little feet and tail!! He had diahorrea this morning but that seems to have gone normal now but he's just had a drink and was sick after and the mouse was in with a few chunks of food. What do I do?! Will it cause any harm???

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Ziggy! Eating a mouse shouldn't be a big deal. Mice are intermediate hosts for some intestinal parasites and if the mouse died from eating rat/mouse poison it could be a problem. Since Ziggy is a big dog I doubt if the mouse died from eating rat poison he would be affected. As long as the vomiting and diarrhea are self limiting he should be ok. Hope this helps!
