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.
