Bear does the same thing, but the problem is he won't eat when anyone else suggests it, even though he may be hungry. Add that to him not being very good at telling when he is hungry life around here is interesting. My best suggestion is that when it comes down to it the type of food isn't as important as simply getting food into him regularly. I try to feed Bear healthy food, but if all I can get into him is chips and that will give him enough calories to stop a melt down, guess what he eats! I've found it is very much a pick your battles situation.
