Sturdy For Chewers; Weeks Later Still Lights Up
This item is fantastic. We have two rottweilers and these two tou balls have stood the test of time. Weeks later and it STILL lights up! No other ball has survived our dogs. I highly recommend this item to anyone. Our dogs love the lights.

The squeak might die the ball does not.
Color: Orange Squeak Toy, Size: Medium
If you want to cut to the chase YES THIS PRODUCT WORKS, if you want more details then continue reading.
So for starters, we have a 75 pound Doberman whom we call "The Destroyer of All Things". Anything she can tear into (toy wise) she will dismantle in a matter of minutes. It's been very frustrating trying to find toys that will last long enough to occupy her playtime without us feeling like we may as just hand her money to shred up and throw in the garbage.
I will say that my dog, however, is also a "picky" destroyer and will not simply chew and destroy and play with just any toy. I bought her a solid hard rubber ball once that weighed a ton and because it was so stiff and had zero give and was actually indestructible (to her standers) but, she played with it for a matter of 30 seconds before never touching it again. If it's too solid and indestructible she gets no satisfaction from it and won't play with it, which is also a waste of money since it's been sitting at the bottom of her toy bin ever since. So trying to find a toy that is a balance of fun for her and durable for our pockets was a hard task, until now.
My husband somehow stumbled upon this ball and hopeful from all the glowing reviews (but still skeptical so we wouldn't be disappointed if it didn't work) we ordered it immediately. We have NOT been disappointed thus far and she's had it for a month!! Just like some reviews have said, the squeak did not last long, but that wasn't surprising. Our dog's favorite toys used to be the yellow tennis style kong balls and she'd have the squeak killed in a matter of seconds until it only wheezed and then she'd tear up the ball itself. Which is why we needed to find a replacement that she could shred into tiny rubber pieces all over my floor.
This ball really truly was not annoying when is squeaked, until the piercing shrieking noise the Kong tennis balls made this one was pretty chill on the noise level and I didn't mind it at all while it worked. If the squeaker hadn't died I wouldn't have been driven up the wall with the noise and bonus my dog still loved it either way. But, the squeak didn't last long, maybe a few minutes at most.
However, I continued and continue to monitor this ball for any other signs of defeat and have yet to find ANY. Not a tooth mark, not a nick, nothing, nada, ZILCH. This ball is soft enough that it has some give when she chomps down on it, but it's durable enough to bounce back and not snap or crack or break under pressure. The give my dog gets from chewing on it keeps her attention because I think it gives her some false sense of hope that she might still be able to destroy it. So even after a month, she's not lost interest.
Also, even though the squeak has died when she chomps down on the ball it sort of makes a clicking/suctioning noise which also makes her very happy to play with it. She loves it when we toss it down the hallway because of the softer rubber it has a rather unpredictable bounce and so she never quite knows where it's going to go.
Highly recommended and I cannot wait to test out other products from this brand and buy her a couple of more balls to have around the house in replacement to her old Kong balls.

Good dog product
Color: Pink Squeak Toy, Size: Medium
We’ve had the squeak balls for many years. The squeaker doesn’t last long with an aggressive chewer. Our dog squeaks the ball so much, she makes the ball split. We remove the squeaker and the ball continues to be used for a few years until it splits enough we throw them out. The ball has good bounce. We leave them outside all year and they have lasted thru snow and hot weather. The ball has been 2 of our dog’s favorite toy.

Extremely durable even for destructo-dogs!
Color: Orange Squeak Toy, Size: Medium
I got this for our chew-monster Bruce, a very large German Shepherd & (we think) Great Dane mix, after he repeatedly demonstrated his ability to utterly destroy the large Kong squeaky tennis balls within a matter of minutes. He LOVES some squeak, so he obsessively squeaks his toys until they're crushed. After some research on longer-lasting toys, I splurged on one of these, fully intending to guilt the dog forever if he destroyed this much more expensive toy. It's been 2 months, and this ball is not only still squeaking, but it isn't chewed or destroyed AT ALL, despite Bruce's best attempts! It's smaller than his other balls, and because it's a slicker texture, it slides out of his mouth more easily. However, it squeaks when it hits the ground, and he can entertain himself with it for long periods of time.
Pros:
- Super durable
- Squeaker is molded in so it can't come out (unlike the other toys we've bought)
- Bright orange is WAY easier to see in the grass than stained green/yellow tennis balls
- Easy to clean
Cons:
- I wish it were slightly larger, because his mouth is so big. No issues with swallowing it or anything, but if they had an XL size (like other super-large sized balls) we'd go for it. Orbee, let us know if you decide to upsize!
- It doesn't squeak quite as easily as other squeak balls, but Bruce figured out how to make it work. He sometimes will even hold it against the ground to squeak it faster.
- It doesn't squeak as loudly as the faux tennis ball kinds, but wait...that's not a bad thing. It's still loud enough for him to enjoy, without the neighborhood rioting.
Overall I can't recommend this toy enough. We feel safe letting him play with it since the squeaker can't come out, and it's paid for itself repeatedly - we were going through a 6-pack of squeaky tennis balls per week (or more!), and haven't had to buy any in the last 2 months because this ball is still in pristine condition.
