Is a well behaved dog, just a recipe away?  According to Jeanne Perciaccanto, a certified dog trainer, your dogs food may be the key to good behavior.  Perciaccanto found that hyper and out of control dogs are most often fed dog foods that have higher levels of wheat, corn and corn meal, while aggressive dogs are fed dog foods that have incomplete proteins that do not digest well.  So if your dog is misbehaving, it might be time to consider breaking out the cookbook.
