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
