They are very hard to tear up! Definetly for aggressive chewers!!!
Color: Blue
Dogs love them!!! My 70lb bernese mountain/hound dog mix loves them!!! Taking her long time to chew through them!!! Unlike other chews which would have already been destroyed!!!!

Durability
Color: Blue
My Princess loves playing and chewing on these. She alternates between all 3. It keeps her busy from chewing on my slippers. Very durable toys.

Perfect for my dog that destroys everything
Color: Purple
It’s important for you to know: it’s hard. It’s a hard toy. It’s a bit heavier than normal dog toysx but it’s perfect for dogs who destroy every toy.. I have a 30lb 2 y old baby and they keep her entertained for sure. They are s good size. I honestly love it. My dogs love it too. It was a good purchase :)
