Ok, so my lab mix puppy, Rex, is a little bit of a chewer and he puts everything he sees in his mouth. Well I was walking him around the yard today and I spotted a dead mouse, just not quick enough. Rex had that thing in his mouth in no time and before I could pry his mouth open he had the whole thing swallowed. Is there something I should do? I mean I'm feel like he should be fine, but I'm new mom....I'm worried!
