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!

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!
