Very fun toy at a great price
Color: Monsieur Acorn - Large
My dog (an American Staffordshire Terrier) lovessss to chew and destroy things! We have literally gotten three of these because she loves them so much, and they last, too!! You get the first toy, which my dog rips open. I’m not sure exactly how long it takes for her to destroy it, maybe a few days to a week. Then another little toy (with a sad face lol) is revealed. She highly enjoys this one, as well! Finally, she rips the fabric off that and then a blue, spiky ball is revealed. She lovesss to chew on it and I think the bumps are a nice texture for her mouth. She is quite a strong chewer and the ball lasts a long time!! No toy lasts forever and I have found under dog toys are quite expensive and that’s no guarantee of how long it will actually last. But I am perfectly fine with spending ~$11 every once in a while for these toys because I know she loves them, and they are not immediately destroyed.

Would happily purchase again.
Color: Hedgehog
My powerchewer of a dog destroys plushies in 10 minutes and most other 'tough chew' toys don't last more than a day or two - at most. But he loves his hedgehog and hasn't managed to destroy it! Sure, it has a plethora of teeth marks, but it's in one piece and he hasn't managed to bite off any chunks (I was worried about the hedgies nose 😂). It stands up to his teeth and allows him to satisfy his need to gnaw & chew, safely.

Excellent, But Not Strong Enough
Color: Monsieur Acorn - Large
This has become the most engaged my dog has ever been with a toy. He chewed these acorns for an hour and a half STRAIGHT. Sadly, he was able to shred both acorns by this time.
For dogs with a normal chewing and shredding amount, this toy would be perfect. However, for a super chewer like our dog (Lab/Malamute), it seems like we're going to need something stronger...
