    Actually stands up to use
    Size: 4.5", Size: 4.5"
    I have a pitbull who is a toy destroyer. All those toys, even the ones that say tough enough for destroyers, never hold up. THESE BALLS ARE AWESOME! I bought the 2 pack of the 4.5 inch balls and they lasted a year. I literally am writing this review after ordering a new set. These are well worth the money and Ghost (my dog) loves them. Hes a 103lbs pitbull and his life mission is cuddles and destroying his toys... and these lasting a year of everyday use is friggin awesome. Both toys failed in the same way eventually. They gave out in a circle around the "squeker".

    One of the best dog toys I’ve found
    Color: Blue, Color: Blue
    My Great Dane puppy- at 140lbs, loves this!! We had another one that was plastic and it worked ok but this is so much better! Interactive, soft to play with, battery last a long time & he does not get bored with it. Besides is plush lamb chops, best toy ever bought for him.

    Keeps my wild child busy!
    Color: Orange
    *UPDATE 1/10/26* Does my pup love it? Yes. 5 stars for that. His big thing is just holding it in his mouth though, and laying down with it. Then he will put it down, and as soon as it rolls away he gets up and grabs it again. He definitely requires attention from his humans when it’s turned on…kind of defeats the purpose of why I bought it! He’s a needy boy, that’s for sure, so it’s not the toy’s fault. Two improvements I’d love to see though, are 1) the ability to turn off that yappy bark. I think my dog is more excited about it moving and not so much the yapping. Not that it’s bad, but my boy doesn’t bark much so I’m used to a quieter household. And 2) when removing the base for powering off, there should be a sensor so it doesn’t keep spinning in the socket, occasionally slipping out and hitting the floor. I worry about it breaking due to this. This thing arrived today and we couldn’t wait till Christmas to give it to our high play drive Australian Shepherd. It’s been barely above zero for weeks with no end in sight, and I have cold weather asthma so I really try to limit my exposure to the elements. Needless to say, my dog has been B O R E D. He truly craves interactive play with his humans, but last week I bought a cheap r/c cat toy that really caught his attention. So I splurged on this toy and so far, it’s AWESOME. He can’t control himself when the rope starts spinning. He pounces on it and it goes spinning off and around. He keeps picking it up thinking it’ll stop, but it keeps going. After 5 minutes of play he was acting completely gassed, but he just can’t resist it, as he put it down to get a drink of water and it started spinning again. Forget the water, I need that toy! As long as this thing can handle the teeth, slobber, dirt and grime, I’ll be a repeat customer!

    My dog loves it...but needs charging four, five times a day. You really need 2 for full-time play
    Color: Blue
    My dog loves this toy. The first time she saw it and it started rolling, bounding, and waving the ropes around...she was barking at it, chasing it, grabbing it, jumping all over the place. There is no other toy she has that she will leave this for. And...that's part of the problem. I have to take this away from her three, four, five times a day to recharge it. The charge barely lasts an hour and the toy is dead. And it takes over an hour to charge it all the way up. Which means she plays with it less than it spends charging. That's not ideal. The product page and manual that comes with the toy says there is a 10-minute play period followed by a 30-minute interval to let the dog cool down...not get overly stimulated. I have never seen a cool-down period. I don't know if it's because the dog plays with it, shakes it around, tosses it and chases it, etc., etc., etc. constantly...but it just keep going until the battery is dead. I wish it did have a cool-down period. She likes playing with the ropes and rolling it around herself even after the battery dies, so if there was a cool-down, maybe it wouldn't need to be charged many times a day. Once it's charged and she sees me putting it back together, she gets very excited and starts jumping up and trying to grab it. Our corgi reduces most rope toys to threads in a day or less, and this one has held up surprisingly well against her super-chewing habits. The material the ball part is made of is very durable (we have a couple other toys with the same type of shell) and she's chewed on them all a lot without any damage. The toy keeps her entertained and happy...when it's not on the charger. I wish it was a good-enough value for the money to be able to justify buying two of them so I could have one charging while she was playing with the other. ================= I'm adding 1 star, because the company customer service is outstanding. They emailed me about my concerns vis-a-vis the short battery life, and it seemed that they really listened and cared about my input. I don't know what, if anything, can be done to extend the battery life given that it's spinning some substantial pieces of rope around, but I think they'll do as much as they can. In the meantime, my dog's love for this toy has not diminished in the least. She still gets very excited when she sees me starting to put it together after it's done charging, and she ignores everything else (sometimes even offers of treats) to play with it. I have a second one now, and I can almost keep them going full-time, but the few minutes every couple hours when both of them are on the charger is probably good for her anyway...she'd probably be over-stimulated if she had one of these to chase non-stop. Summary: Great toy, lots of fun, my dog loves it. However, you really need two the way things are right now unless you are okay with your dog being able to play less than half the time.
