You might think every dog should automatically know how to eat his food and be more than ready to do so as soon as you put his bowl down. But, not all dogs will do so; some are fussy and will spend time sniffing the food, licking it, and looking at it, yet he still will not eat it. What's going on? Isn't he hungry or maybe he just doesn't like his food? If you are under the impression that the reason he won't eat is that he wants variety in his foods, it's possible that nothing could be further from the truth. The simple fact is, your dog will keep eating the exact same food day in, day out for the rest of his life.
It is your job to make sure you offer him a tasty nutritious meal. In fact, chances are good that the biggest reason he won’t eat his food is that you have probably been feeding him table scraps. When he gets used to these tasty morsels, he isn't going to want the dry or canned food you have been putting in his dish. Or perhaps you started him out by offering him several different types of food to see which one he liked the best, now he is simply holding out for a better food. No matter what the cause, now you have to teach him to eat the food you put out for him.
In this particular case, there really isn’t a specific command to teach, such as "Eat" or "Chow Down". It is important that your dog learns to eat, but at the same time, if he takes a day off from eating, it is usually nothing to worry about. Not all dogs eat every day and some need to eat more than once a day. In most cases, training your dog to eat what you put in his bowl is nothing more than a matter of time and patience. You can teach a dog of any age to eat what you put out for him; in most cases, it could be no more than waiting until he is hungry enough to eat.
Remember, your dog will not starve himself to death, he will only go without eating until he can no longer stand being hungry. Be patient and in time he is sure to put his nose down in the bowl and start scarfing down his food.
If your dog is being fussy about his food or seems to be refusing to eat what you put down, patience is the only real tool you need. Be sure to keep his food bowl in the same location at all times and pick it up when he is done eating. Try to pick a quieter spot in your house such as the kitchen floor and choose a time when no one is likely to be in there to disturb him while he eats. Again, there aren't any real commands you need to use to make him eat, you just have to be patient.
