I have 3 large dogs that are proficient at destruction and extremely aggressive chewers. Few toys survive them. I bought several of these toys and they have been put through the ringer but still in great shape. Definitely worth it in my book. I wish there were more cute options but cute doesnt typically last for these 3.

My dogs go CRAZY for these!

Color: Ring

My Pitbull and Frenchie go CRAZY for these! They do have a leathery type smell to them if you’re sensitive to that (doesn’t bother me) and my dogs WILL ingest what they tear off if I don’t watch them closely. Only removing 1 star because of how fast my dogs tear these apart and how deliciously enticing they apparently are to ingest, but my dogs may just be psychopaths. :)
