what are you feeding him; maybe he doesnt like the food; yorkies tend to be very picky eaters. i had this problem for almost 2 years now with my dog; she wasnt eating and drinking at times; she ended up in the hospital twice with gastritis and dehydration. until finally i switch food to the honest kitchen; i feed her 4 small meals and i add digestive enzymes and probiotic; so far so good.
just to make her to eat something; boil some chicken and rice; if not then you can give baby gerber food; my vet told me to give her that for 2 wks after the hospital stay and then i switch her to the honest kitchen; and of course the added digestive enzymes and probiotic are life savers. good luck
