Fantastic toy for aggressive chewiers!
I have bought two of these for my granddaughters three dogs and they love them! In fact, I only bought one to see if they would, and all 3 played with it! One is a 5 year old pit mix, one is a 9 mo. lab mix, and ine is a 10 year old shepherd mix! Miss Lab goes through toys like melting ice, so they reall have to be well made. Not even Kong toys have made it with her! All three dogs have made it squeak, which we didn't know it did! If you have an aggressive chewier, this is the toy you need to put in the #1 spot on your list to buy!

Long lasting toy for destructive doggos
Nice toy and seems to be indestructible even with two Boston Terriers trying their best to destroy it.

Great chew toy
My dogs love this toy and we still have it a month later. That’s impressive since they are aggressive chewers.

Great buy
My dogs absolute favorite! Super durable and keeps him busy forever. The squeaker is fun but it’s nice because it’s not an easy squeak so the annoying part of it is actually tolerable. The size was perfect for my 100+lb German Shepard. I’d buy 100 more once he dominates this one.
