Finally a Toy My Pitbull Hasn’t Destroyed in 5 Minutes
Color: Blue+Red, Color: Blue+Red
I have a 65 lb pitbull who destroys most toys almost immediately, so I’m always skeptical when products claim to be “indestructible.” Most toys last maybe a few minutes in my house before pieces are everywhere.
These have actually held up surprisingly well.
The material feels durable and thick enough to handle really aggressive chewing, and so far my dog hasn’t been able to destroy them like he does with most other balls and squeaky toys. That alone makes these worth it to me.
I also really like the size. They’re large enough that I don’t have to constantly worry about him accidentally swallowing them or choking while playing, which is a huge plus for bigger dogs.
The squeaker inside also keeps him interested longer since he usually gets bored quickly with toys that don’t make noise or bounce around well.
If you have a strong chewer or larger dog and you’re tired of replacing destroyed toys constantly, these are definitely worth trying.

Excellent choice
Color: Red+Orange, Color: Red+Orange
I will skeptical when buying these because I have a pitbull bulldog that likes to chew holes in every toy. This is her favorite she choose on the ball, but she doesn’t actually ruin it because she can’t. It holds up one of the squeakers broke, but that’s expected I guess my wife actually ordered more. I’m not sure if it was from the same seller or not but those ones they don’t favor as much for some reason I seen the same different colors. My dog even sleeps with it sometimes. The picture shows for sleeping with it. I’m definitely happy. I got these. They are tough. I like the fact that they have those little recessed holes so they can grab a hold of it and not get it all slimy like the other balls we have.

GSD Winner
Color: Blue+Red
10/10 recommend for big dogs with a tough chew. Our GSD absolutely loves these squeaky balls. They have perfect texture for his teeth and for our grip. They are the size of a baseball and are so durable and fun. Yes the squeaky is LOUD but he loves them so much that it's cute

Still in one piece and still squeaks--that's a win with my Pitbull.
Color: Blue+Red
Great toys for my dog.
I can't say your dog won't chew through these, but my little Pitbull who chews through most 'tough' toys within 15 minutes is still working on these. Both are still intact and still squeak two days later. And that's something for her. She's a master at surgically removing squeakers from toys. I'm happy.

Great buy
Color: Blue+Red
My dogs kill every toy. They arrived very agressive chewers. These have lasted way longer than most balls have. Great value
