Q. My yorkie started shaking and hiding today. He has not eaten or drank anything today. I am starting to get concerned. This is not like him
A. Sounds like he is not feeling well at all. Check the house and see if there is anything he may have gotten into that he shouldn't have. If you can't seem to find anything continue to closely monitor him. Not drinking is more concerning as they can dehydrate quite quickly. If he still isn't showing interest in food or drink it would be a good idea to book a vet appointment to eliminate something more serious. You can always try to tempt him with sometime like low sodium chicken broth in the mean time.
