My dog is a 2 1/2 yr old dachshund/terrior mix. We give him table food and dry and canned dog food. He is all but refusing to eat his dog food. What`s to do?

Stop giving table food he is liking that more and holding out for it. The dog food meets his nutritional needs. It may take a while for him to realize that there is no table food but a dog will not starve himself
