Hi! My dog just started acting weird…! He was fine a few hours ago! He was asleep then all the sudden he wakes me up whining and pacing around the room like crazy!!! He was also attempting to throw up but nothing ever came out! He is chewing in ANYTHING he can find which might sound normal but he doesn’t chew on things at all…unless it’s a bone! Please help! He won’t stop and he has been at it for hours!
