Good for play but don’t leave out to be chewed on
With two labs we need durable toys. This can stand up to the teeth when pulling but we can’t leave it laying around or it has chunks chewed out of it. And it’s not the toys fault that my girls can’t figure out how to each take a side, so it’s a human vs dog pull toy.

Toy is strong enough for a Rottweiler.
This is one of my dog’s favorite toys. He is a Rottweiler so I have to get him strong, sturdy toys. He hasn’t broken it yet!

Will buy again
Perfect tug toy. My big guy is an aggressive chewer with some strong jaws. I'm extremely impressed that its lasted as long as it has. He loves to play with it, tug on it, chew on it. Exactly what I had hoped for.

Buy it you won’t regret it
This is the best toy ever! My Rottie loves it and can entertain herself for quite a while. The unpredictability of its bounce when tossed keeps her guessing and moving getting lots of energy out. Great for tug as well, or roll it on flat surfaces, it’ll go forever! She love the squeaky too

Best dog toy ever!
We saw someone with one of these at the dog park and thought that it would be perfect for our male Boxer, Buster. He has torn up just about every toy we’ve gotten him and this thing seemed really durable and really fun. Buster absolutely loves this toy! It is definitely the most expensive dog toy I’ve ever bought, but we’ve had it for months, he plays hard with it every day, and it is perfectly intact still! I wish I had known about it sooner so I wouldn’t have wasted money on Toys that he destroyed quickly. If you don’t like squeaky toys this may not be for you because once they figure out how to get it to squeak, you’ll be hearing it often. The nice thing is it doesn’t squeak without a lot of effort and it takes a strong dog to get it going. It doesn’t squeak when it’s just rolling around so that’s a plus. It is big and heavy though so be careful not to trip over it! Fortunately, it’s easy to spot with the bright color on one side. Highly recommended!
