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🤣

Great Product!

Size: 5.75 inch (Pack of 1)

My dog is a chewer! She can chew through most chew toys in a day. This has been a lifesaver! She chews on it but has not been able to get any pieces off of it. It is Durable and she loves it! This is a great item. I intend to buy more like this. It is a great product!

Amazing toy for large dog breeds!

Size: 9.5 inch (Pack of 1), Size: 9.5 inch (Pack of 1)

My puppy Rottweiler loves this toy! Withstands her heavy chewing and really seems to soothe her! It’s very loud against the floor. She struggled a bit at first with picking it up but now it’s no problem. Highly recommend for big dogs

My puppy's favorite stick, high quality

Size: 5.75 inch (Pack of 1)

Perfect quality chew toy for my dachshund puppy. She will spend several minutes everyday chewing on this. It is the perfect size for her small mouth and it doesn't show signs of wear like most sticks do.
