there is something wrong with my dog, and i cant get him into the vet right now because they want 300 just to walk in the door..he keeps digging holes under the fence and i guess he got out and got into something or something happened because we found him laying in the neighbors yard..hes shaking really bad but he will wag his tail at you. he doesnt have blood anywhere and he has foam coming from his mouth. i put him in the room where we have our goats last night..gave him a blanket with lots of straw under it and plenty of water..and this morning we found him in the neighbors yard again, in a freshly dug hole! i dont know what could be wrong with him! is there anything i can do for him until i can get him in somewhere?
