Chewing and gnawing is beneficial for their teeth, gums, and jaw muscles - adult dogs can clean their teeth, massage their gums, and exercise their strong jaws through gnawing. Puppies and juveniles often gnaw during teething to relieve itching or pain.
Chewing can help dogs cope with being alone for short periods. By providing a private space and plenty of time to chew on a snack-filled toy or a raw bone, dogs can learn to spend time alone, reducing the likelihood of developing separation anxiety. It is essential to provide a chewing toy and something to do when leaving a dog alone at home.
