Take him to vet immediately. An old friend of mine has a 2 lb yorkie that wasnt supposed to live, and yet she still has her. She has the hypoglycemia. She also wouldnt eat and they had to give her baby formula in a syringe and pedialyte. She is also on viagra...believe it or not!
Completely agree with Misfits. It could be any number of reasons and your dog needs to be checked by a Vet. A dog that small can also get hypoglycemic.
