A chew toy is an object designed to be chewed on by animals for stimulation and relief from boredom or discomfort.[1] Chew toys can help relieve pain associated with teething, which is especially true for younger animals, such as puppies.[2] There are several types of chew toys made from different materials, including rawhide, wood, paper, and mineral. Chew toys are commonly associated with dogs, but have also been effective with birds, rodents, and rabbits. Some parents give human infants a similar toy called a teether to help soothe inflamed gums during teething.
