Puppies are adorable, but teething can be a difficult time for both him and your family. Introducing your puppy to age-appropriate dog chew toys early can save your precious household items. Chew toys designed for puppies are a little smaller and softer than the adult toys are, because puppy teeth are more prone to fracture. Ensure your new dog is getting a properly balanced diet, including vitamins and minerals such as calcium, so that his new adult teeth can develop normally. Having two teeth crowded into a space meant for one can cause discomfort and possibly initiate some destructive tendencies in your pup.
