Natural Balance Dog Food Petco

My dog is a very picky eater when it comes to food and candy, what I can do?
Our dog is a miniature schnuazer. She has 2 years, 12 pounds and is very active and lean. It is a dining room, very demanding. She hates dog food and no table to eat much less food is mixed with it, and even then table name is the spitting food or dog food. She hates candy for dogs, so it is difficult to train as well. She loves these treats that look like cookies of animals that are petbar at Petco. We tried all kinds of dog food and he hates that. Beneful try (hard and soft food), Iams (hard and canned), sausages balance PETCO Natural Food Research, and now we have been feeding Science Diet for about half a year. Having a Also our friend dog loves play our dog all the time and eat dog food when you are at home (which is Iams), but if we offer the same food at our house is not eaten. We know it's unhealthy for her, so what can we do for our dog to eat his dog food?
Boston Terrier My mother is in the same way. He eats about three bites of food almost every day. She was a lot of food and nothing seemed to work for good. Completed the purchase of dog food at low prices Wal-Mart called dinner Rounds and she loves him for any reason. She always goes up through these spells when my mother put some sauce on your food b / c you can not choose the sauce on food b / c it absorbs. This does not seem to help most of the time, but still there are days when the dog does not eat. Training to use cooked chicken or liver are good for her and help you learn faster b / c you really want the reward!
