Great purchase!
Color: Red, Color: Red
I have 3 very different dogs, a Doberman, a rat terrier, and a German short hair - Great Pyrenees mix. They all LOVE these durable chew toys. I will definitely be purchasing more when the time comes. I wouldn’t need more due to durability but my rat terrier is an expert toy hider! 😅
