A total joke.
Pattern Name: Cage Ball, Size: Large - 4 Inch / 8.5 oz
I was so hopeful and really wanted this to be as good as the sellers claimed. After all, they boast of a lifetime replacement (a joke and be sure to read the ridiculous terms lol). I have a "pocket pitty" and she loves rubber toys. There is not much I have found that can withstand her force; however, reading reviews AND seeing their warranty, I wanted to give it a try. Typically, I stick with Java wood and XL super dense knotted ropes, as that has been the only thing that can last any real amount of time. Thankfully, she never goes after our stuff or household items/furniture, just her toys.
The ball arrived. I checked it over. It looked semi promising. I was hopeful. The design does allow for them to leverage their paw strength by getting it between the rubber bars and then pull with their teeth. Within 3 minutes of her having it, she already had a bar ripped off. Within 5 minutes, she had 3 bars ripped off. Don't get me wrong, she had a blast. But this is by no means strong enough for an actual aggressive chewer. Perhaps there is just not anything rubber that can handle her jaws, but now I can't get a replacement because the warranty only covers if the product is defective. It doesn't cover chewing damage (on any of their products). The advertising is very misleading so be aware. Why a replacement if she will just destroy it again you may wonder? She loves to go after a ball, but now I know she can kill this one, I keep them in a drawer and only let her play fetch with it while supervised.
I will say though, I you have a puppy, I think this would be great for them as long as they are not extra large. The material has give, which is nice. But if you have a real aggressive chewer, don't waste the money.

Not indestructible, but is very tough.
Pattern Name: Ball, Size: Large - 3 Inch / 12 oz
My dog destroyed this, but it took a little longer than it usually does. Would love to know how the lifetime replacement works. There is no information that I see on how to contact the seller.
