This bone has held up to my dog who is the destroyer of everything. She loves this thing, chews on it all the time and its the perfect size for her. Great value for the price and will purchase again in the future once she gets tired of it.

very strong for puppies with strong jaws.
Color: Brown-O, Color: Brown-O
I have a five month old puppy and she was having very bad teething. I know every puppy goes through it and it's usually a nuisance because they chew shoes or things that you don't want them to chew. This puppy would find a plastic coat hanger and try to chew it with her back teeth. I think she was cutting her molars and it was hurting her. She wasn't eating and she was drooling and whining. I felt so bad for her. She was trying to chew anything that could reach back to her back teeth. This product really helped her because it got back there and it is really strong. She is a Pitbull puppy and she already has a really strong jaw so a coat hanger didn't last long. This Teething ring did help and it got her through the worst of it. I really like it for that reason. If you have a teething puppy this is the right way to go. It doesn't squeak and it has a flavor that kept her coming back to it but the it didn't have a funky smell when she left it around like hooves or bully stick do. It also has a bumpy, rough surface that must have felt good on her gums.

Durable, fun, and good for aggressive chewers
Color: grass-green
I have bought this toy for my dog twice now, and the first time I purchased it, it quickly became his favorite. Unfortunately, I lost the first one when some other dogs took it down the street while we were playing outside. It was a bit heartbreaking to lose it, but after about two weeks, we managed to find the old one. However, it was in the middle of the street and had been run over several times, resulting in a broken squeaker. Despite its rough condition, it was clear how much my dog loved that toy. When I bought the new one, I was relieved to see that he doesn’t let it out of his sight at all. We have so much fun together, playing with it by throwing it in lakes, sandy areas, and engaging with other dogs. Even after all this rough play, the new toy is still intact. My dog particularly enjoys the squeaker feature, which adds to his excitement during playtime. He is an aggressive chewer, but this toy has proven to be more durable and has lasted us much longer than most of the other toys we've tried. It has definitely become a staple in our playtime routine!
