Recognize the signs of obsessive behavior. The the dog's eyes glaze over and the only thing they are paying attention to is the item of their obsession. When this happens, it is time to react. Cesarsway.com compares this behavior to that of someone who is addicted to gambling -- their eyes and mind stay on the cards. When talking to the dog, the dog will not respond in any way.
Correct their behavior immediately. Don't take away their object of obsession, but use the place of the pack leader to get them to walk away from the item on their own. "Dr. Pitcairn's Complete Guide To Natural Health For Dogs &Cats" suggests that just removing a troubled object from a dog's life is not always the answers to a dog's problems. Try distracting them with a treat or attention if just calling them off does not work.
Take the dog for a walk on a regular basis. A dog that gets enough exercise is less likely to have obsessive behavioral problems and also will be less anxious. For canines, fitness is just as important as food.
