Sean Moore  asked the Naked Scientists:

Do wolves or dingoes chew on sticks or bones like domestic dogs do? Why?

Sean Moore

What do you think?

Wolves certainly do, and I would imagine that dingos also do.

Chewing on sticks is good for the teeth and the jaws (although splinters can occasionally damage the soft tissue inside the mouth). I suppose it's some evolutionary development for keeping their teeth healthy.
