Got this a couple days ago and so far very pleased. Would give it 5 stars, but only had it a couple days - we will see how it holds up o er time. All 4 of my dogs love it, so much so that I ordered more today. It's got an awesome squeaker, and is flexible without being flimsy. My guys haven't destroyed it yet, and that's always a good sign.

Good quality, great for the beach

This is great for ocean and beach fetch! The spikes keep the sand and saltwater from getting in my pups mouth and upsetting her stomach. It also floats well and doesnt fill with water. I have had this for about a month now and in surprisingly good shape considering how obsessed with it my dog is. Not gonna lie, I avoid squeakers since my dog is an absolute menace with them but i assumed the squeaker would break almost immediately, however it is still going strong much to my annoyance🤣
