Chewy is scared of any kind of smoke. i was cooking bacon and he shook like crazy.. he ran around with his tail between his legs, very unhappy and would not be consoled... We had no idea what it was. He also sat by the door! After cooking bacon a few times we saw that he was scared, I burned some bread in the oven last week and he acted the same way... Tonight we have a fire in the fire place and at first he was scared but little by little he got closer and decided it was no threat... He seems fine now. Maybe your yorkie is scared of something and you don't know what it is yet!!! Just a thought!
