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...

A favorite for my small destroyers

Color: Monsieur Acorn - Large, Color: Monsieur Acorn - Large

My small destroyer dogs LOVE these toys and are always surprised to find another toy after the first and second violent de-stuffing. Definitely a supervision toy for safety, but my terriers love doing their thing when these come out and they last much longer than I had anticipated. Color, design and value all as described, however I literally do not remember if it did squeak because the squeaker would be the first thing gone
