Chewing is a natural behavior for all dogs. It allows them to explore the world around them, exercise their jaws and even clean their teeth. Most of all, it engages them mentally and alleviates boredom. However, when dogs lack the proper items to chew, it can lead to destructive chewing and other behavior problems. Providing plenty of dog chew toys is one way to allow your dog to fulfill his natural desire to gnaw on things. Supplying your dog with tasty, edible chews is another way.
