Finally! A toy my aggressive chewer cannot destroy!! Can’t even get the squeaker out! No other toy has ever held up and it’s got some nice bounce to it. Perfect size so it can’t get stuck under the sofa. Furthermore, it aids in cleaning his teeth and he loves them. This is a great money saver too! Update - 3 months later - still pup’s fav…still whole - still lotsa bounce - still has squeaker intact. As good as new! I’d buy these again but don’t need to 😃!

Toughest ball of this type.

Color: Blue

My dogs are brutal with these toys. I really like them as the spikes act as a tooth brush, and the dogs love knawing on them. There are other spiked balls like this on amazon, but this one is of better quality. It lasts a lot longer. The squeaker does not last long, the dogs teeth push it into the ball, you can hear it rattling around in there.

Very good for aggressive chewers

Color: Red, Blue, Green, Yellow

Finally found ball that my aggressive chewer doesn't destroy. Has loud squeaker however he broke after 4 days. Probably better, noise gone. Very sturdy and he loves. Also big so doesn't roll under furniture.

Durable

Color: Purple

I bought this for my 80lb 1yr American Bully male,who has made it his mission to test all the toys his dad and I have bought. Now I have 3 other American Bullies, siblings 3yr old 2 females/1male, who did the same at that age and I mastered toy shopping or so I thought. Lol. My new pup loves balls and this is the only one he firstly can't fit completely in his mouth and can't tear it apart. He has tired!

My Dogs Loved Them!

Color: Purple

My dogs loved these for playing fetch. They seem heavier duty than previous ones I have had. Beware of the incoming constant squeak sounds if your pup gets really into chewing it.
