My labrador Guide Dog cracked a tooth on a Nylabone , and after the tooth was removed, The dental vet tech suggested getting rid of all her Nylabones and replacing them with Hurlys. The large Hurly was an immediate hit. While she doesn't gnaw on it continuously, she absolutely loves it! It's the go-to toy when someone rings the doorbell, when she decides that it's time to play fetch or tug and sometimes she just carries it around the house.
