We picked up our dog Toby yesterday after boarding him for one day. He was constantly trying to swallow like he had something stuck in his throat. We took him to an emergency room for pets and the vet removed a piece of grass that was stuck near his tonsil. However, he still trys to clear his throat occasionally and is very lathargic. He has no appetite and drinks very little water. He has been eating grass, which is not his normal behavior. He just had a spell where he was coughing like he was trying to clear his throat.
