TLDR Bullet Points:
1. Denying dogs chewing opportunities may pose welfare concerns.
2. The shearing/abrasion forces during chewing help clean teeth surfaces and may reduce periodontal disease risk.
3. Chewing on harder substrates may stimulate bone remodeling in the jaws, strengthening bony architecture.
4. Chewing helps regulate the autonomic nervous system, reduce stress, and provide an outlet for behavioral motivation.
5. Chewing is a biological need for dogs.
6. Chewing on harder substrates may stimulate bone remodeling in the jaws, strengthening bony architecture.
7. Chewing appears to be biologically beneficial and likely essential to both physical and psychological well-being in dogs.
