My pups have bones, pigs ears, hide chews etc from 3 weeks old, the sooner they learn what they can chew the sooner they don't chew your furniture, shoes, etc. Also give her the middle of toilet/kitchen rolls, plastic milk bottles or drinks bottles, even cardboard boxes which she can chew and roll round the floor. Also old socks knotted together. Cheaper than toys and safe if you take off any tops etc. Pups need to chew to loosen their puppy teeth to get their adult ones through.
