Chewing is a natural behavior for all canines, and should be channeled appropriately rather than discouraged or punished. Directing your dog towards chewing on rope, hard rubber and nylon toys will help to improve oral health by scraping and cleaning the teeth, reducing any build up of tartar or plaque. Allowing your dog to chew on appropriate items will help to relieve boredom and destructive behavior, and can help nervous dogs or those with separation anxiety.
