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.

These are ADORABLE!
Color: Tropical Pack, Color: Tropical Pack
These are adorable! I got them as a gift for my in-laws pups and when I was taking pics of them my dog now wants them soooo I’m going to order more for her! They are so soft and the details are hilarious! Just be careful because the pawcohol content is pretty high so I’m sure your dog will be feeling it after just one! 🤣🤣🤣🤣🤣

My dog loves these toys!
Color: Original Pack
My dog is obsessed with these toys! We jokingly say that he’s a “doggie alcoholic” because he seems to not destroy any toys like this. They’re very soft and each of them has a squeaker! He’s a German Shepherd so they’re a little on the small side, but he loves them none-the-less! Wouldn’t recommend for tough chewers if you’re looking for something that lasts, but they’re cute and fun either way! Love the fact that they’re made by a small business as well. Will have to update with a picture in a bit!
