My dog has been off her food for two days

Dogs go off their food from time to time, which is fine, but after the third day I would call you vet to have your dog checked, do not try to temp your dog with table scarps. This is a common mistake with pet owners. The best advice I can give you is to wait and see what tomorrow brings if your dog is not eating call your vet, you could also research you problem at Pet Education.com You will find it very helpful.
