Best dog toy on the market
Size: Medium (Pack of 1)
Our blue heeler doesn't go anywhere without this bone. He can chew on it till the cows come home and he doesn't get through it. Rebar enjoys it, plays with it for hours, it's a perfect size for both small and medium sized dogs, doesn't squeak and is easy to throw and retrieve.
