Well, he seems fine now. I took him to the vet and "it's a mystery" He seemed to feel better once my husband came home at about 1 he ate and drank and did his business. I took something out of his mouth but i 'm not sure if he had just found it or if that's what was causing the irritation. I'm just glad he is back to normal. Thanks for all the help and suggestions. I plan on checking him before bed every night form now on. It's just worth it.
oh and my yorkie weighs 11 lbs oops, better change that.
