Winner !!!
Color: Orange
This amazed us. For perspective, we're talking about a three year old white german shepherd who if he's in the mood, has and can kill a toy within minutes or oddly enough be gentle with furry balls and carry them around as if they are his babies. He's an odd duck. Anyway, since he was a pup, and to this day, he'll play and entertain himself, he'll grab a ball, throw it up in the air, then pounce on it as if it's from outer space. It's really quite cute and funny. Because of those two things I was looking for something interactive that would entertain him and confuse him....let's be honest, watching a confused dog is one of life's great pleasures. I tried two other interactive balls and they were crushed immediately. After reading a lot of reviews, people with german shepherds said this ball actually had a life span. I thought the third time could be the charm and ordered one. Well, I think it actually may be from outer space because he's obsessed with it and hasn't taken a bite out of it. He hasn't once chewed it or even teared little pieces off. The three settings are great. Sometimes he likes one better than another, then forgets about the others. I'll change it up to one he hasn't seen in a while and the whole game starts over again. He'll throw it up in the air as he does with his others, watch it and try to figure out which way it's going to go. And yes, he will pounce on it if he times it right. The size is perfect, it's heavier than your average ball but, that's what make it sturdy. I have to sneak it away when he isn't paying attention to charge it, otherwise he'll sit, stare and cry if he knows it's on the counter charging. It's a lot of fun for all of us. I'm so happy I bought it...... I say give this ball a chance even if you have a beast with killer instincts. I'm buying another for a friends 2 year old golden retriever granddog. Thank you Cheerble.

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.
