My Dalmatian has been enjoying this (large) toy for two weeks now. Firm, big and heavy; thick rubber on it allows a good chew, and it’s durable. So far he’s not been able to bite off a chuck of any of it. He normally destroys toys, and will swallow what he chews off if I don’t intervene.I soaked this “bone” in a film of peanut butter to help get the “newness” scent off. After licking the peanut butter away, he meekly narled on it but after some time he chewed strongly enough to get it to squeak. Lol, he stopped, looked at me, actually surprised it squeaked! Immediately mission impossible began - “must-get-squeaker” became his chewing obsession. He loves this toy, brings it to me to toss so he can retrieve, and chews to make it squeak. I will order a smaller size so he has two different versions. Excellent dog toy for aggressive chewers.
