Cute donuts. Not destroyed (yet!)
These squeaky doughnuts are really cute. It’s a bonus that it comes with two. I didn’t realize that when I ordered. I have two dogs and now they won’t fight over a doughnut just kidding one dog is 14 and doesn’t play with toys anymore. The other one is six and loves toys but for some reason he’s not really into this one maybe this will change but for now he only goes after it if I throw it, I’ll update this review to comment on durability if and when he starts playing with the toy, but for now it’s very adorable because it’s just sitting on the floor. Update: he picked one up only because I put it in front of him to take the photo!

Double the Fun
This two-pack was a really nice surprise. The toys are super cute, soft, and just the right size for carrying around, which made them an instant hit with my pup. He loves having a toy he can easily grab and parade around the house, and these are perfect for that. The plush material is soft enough to make them great comfort toys, but they also have that fun squeaky element that keeps things interesting. I like that getting two in the pack gives a little backup when one gets slobbery or needs a quick cleanup. These are better for gentle play and cuddling than for heavy chewing, but for a puppy or dog that likes soft carry-around toys, they are a great choice. Adorable, fun, and a good value for a two-pack.

Absolute favorite toy for almost a year
My dog’s favorite toy for almost a year. It has held up amazingly. I’m sad it’s no longer available. Please bring it back!
