Great Toy!
Color: Tropical Pack
These are great! I bought last Christmas for our pup- a 17 lb Aussie doodle. She’s pretty rough on toys. Usually pulls the stuffing right out in a few days. But these have lasted all year. Came back to buy her 2 new “flavors” to put under the tree.

Cute toy, not a loud squeak
Color: Original Pack
The toy is a good size for medium to large dogs. It's very hard to squeak it but it's fairly durable and super quirky!

Hana approved, gold star toy
Color: Original Pack, Color: Original Pack
This is, according to Amazon, our 11th set in 3 months. According to Hana, our shiba/chi mix, this toy is immaculate. Crunch score is a 10/10 and the squeak? Don't get her started. High pitched, easy to squeak and protected by just enough crunch and fabric that it actually lasts. In fact, she will tear the toy open before the squeaker gives up. This may seem like a small feat, however most toys last 12-30 minutes before the teefies take the squeaker out of commission. Lambchops last about 15 minutes before the squeaker gives in and fluff decorates the floor. The only reason we buy so many so often is because 1. The teefies do eventually puncture and the moment that happens she guts the poor Claw instantly. And 2. She has about 11 teefies, so the mouth gets kinda icky and due to the crunch, washing these kind of sucks- retains a lot of water and cant dry. So we replace them often even if she doesn't get to the gutting.
10/10. Its her favorite toy. And we've tested a lot of toys.
