If your dog has an eating disorder, you must train them to keep their appetite fit.
Tip: Leave the bowl on the floor for ten minutes and then pick it up, regardless of whether he has eaten. (If your dog is a slow eater, this period can be extended to twenty minutes, but only if he is still eating during that time and hasn’t gone off in search of other entertainment.)
At the next scheduled feeding time, put the bowl back down, again for only ten minutes. Pretty soon your dog will learn that he needs to eat when the food is offered.
