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! 😅

It's a sturdy chew toy
Color: Red
Definitely sturdy for a hearty chewer, but my dog wasn't that interested in it. For a treat I spread some peanut butter on it and the design has grooves so she spends some time licking the peanut butter. And it comes with 3 good size chew toys, so cheap enough to try and your dog might love them. Taking out of packing they did have that meat smell as advertised
