My dog is a massive squeaky toy fan. She's also pretty aggressive with her squeaky toys and they usually don't last more than a month. This one is perfect for her - durable, noisy and bouncy. She loves it. The package comes with six but I only have her one and it's lasted nearly a month which is a record because none of her other silicone squeaky toys have lasted this long. It's perfect for her small mouth too. If you live in a flat with thin walls you might want to enforce a curfew with this toy or reserve it for outdoors because it is LOUD. Wear ear protection if you get migraines like me LMAO

Great squeaky toy!

Best squeaky toy for our 18 pound 'puppy.' Great for indoor or outdoor use and he hasn't punctured them yet!

Good quality, lotsa fun

Not easy to find a sturdy toy for a minipoodle that loves to play rough with his toy. He has not been able to break this into pieces and that feels reassuring that I don't have to worry about little pieces and choking. These things bounce funny and my boy loves playing with it

Necessary for a small dog.

These are great for a small dog! They can get their mouth around it unlike a round ball. My dog is obsessed with these. They are great for making him love a new guest to the house. All they have to do is squeak and throw the toy and they have a new friend!
