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

Doesn’t hold up at all.
Color: Hare - Large, Color: Hare - Large
Received this today, and it lasted less than an hour before it had to be taken away to prevent it being eaten.

Tough and fun toy
Color: Blue
This toy has outlived and exceeded expectations! Our dog loves it! He normally destroys any toy within a week or two. This is our second one but the first lasted eight months.
