Giving a dog a toy is equivalent to shelter, food and love. Dog toys serve different purposes. Puppies, for instance, need toys they can chew on when they are teething because their gums and jaws become very sore and chewing on things provides them relief. Also, playing with different toys encourages exercise, which benefits the pet's overall health. Toys also stimulate dogs' minds, discourage problem behavior resulting from boredom and excess energy, and promote dental health.
