Great toy for dogs
Color: Red
My dog loves this toy, it was well worth the money. And I’m glad it charges with USB and not batteries.

Finally, a Toy That Out-Works My Dog!
Color: Blue
My dog gets bored easily, and this automatic moving ball has been a hilarious and effective distraction. It bounces and rotates on its own, which triggers her hunting instinct immediately. The rope chew attached to the side is a nice touch for some added teeth cleaning while she plays. It’s sturdy enough for a medium-sized dog and the fact that it's waterproof means I don't have to worry when she eventually drops it in the water bowl or takes it out into the melting snow. The *only* issue I have is it starts before I can even screw it back together. It wants to jump out of my hands before I'm ready.

My dogs think this is either terrifying or amazing
Color: Blue
I got this interactive dog toy thinking it would turn my living room into a fun little chase arena for my two small dogs. Technically, it did create excitement, but not in the way I expected. The toy rolls around unpredictably and wiggles its rope like it is trying to escape, which is honestly hilarious to watch. The movement is surprisingly energetic and the different speed modes keep it from feeling repetitive or robotic. The battery life is decent and it charges quickly, so it is easy to keep it ready for playtime.
Now for the comedy... my one year old Silky Terrier is normally the fearless one. He charges vacuum cleaners, interrogates delivery boxes, and believes he is the head of household security. However, the moment this toy turns on and starts moving, he suddenly remembers he has very important business somewhere else. He will sit at a safe distance and stare at it like it might file a police report against him.
The funny part is that when the toy is turned off, it instantly becomes his favorite object in the house. He happily grabs the rope, drags it around, chews on it, and proudly carries it like a trophy. Apparently his bravery only applies when the toy is not alive. I have discovered that in my house this is considered the acceptable mode of operation.
My seven year old Yorkie is even wiser. She took one look at the moving toy, processed the situation for approximately three seconds, and decided she would absolutely not be participating in whatever nonsense was happening on the floor. She calmly walked away and has maintained that policy ever since. She clearly understands this toy and wants no part of it.
Overall the toy is well made, entertaining, and definitely capable of keeping energetic dogs busy. Even if your dogs end up like mine and treat it as either a suspicious creature or a decorative rope toy, it still provides plenty of entertainment for the humans watching the situation unfold. If your dog enjoys chasing unpredictable moving toys, this one will probably become a household favorite. If not, you may at least get a very funny show out of it. 🐶

Just another reason to bark.
Color: Blue
I was so excited to come across this Interactive Dog Toy from Mewzoo, figuring that it would be a great way to give our dog some inside exercise during the rainy season that we have in this neck of the woods. It arrives with a charger, instructions and two ropes that can be tied to it, and it took about 2 hours to get it fully charged.
In order to get it moving, one needs to unscrew the blue plastic piece and that gives access to the control inside of it. It has three speeds, but the faster speeds only seem to lessen the time intervals for when it moves, they don't make it move any faster or further. This is kind of a bummer, because it really does not move very far, it mostly just stays within a foot or two of where it started. So not much exercise potential here, unless you consider barking exercise. Barking is one thing we do not need more of in this household, so this toy is a bit of a flop for us. I imagined that our boy might run circles around it and get a bit more hyper, maybe even grab it by the rope and carry it around for a bit. In the beginning I think he was fearful because he just barked at it of it, and then he decided it was time to eat. As you can see in the video, after only a few minutes with it, it looks like he's decided it's just a nuisance, lol.
The concept is good, and the toy itself is reasonably constructed to withstand some playtime. I just think it needs to have more movement and skitter around better to cover more distance. Then again at the whopping price of $10.99, i really can't complain.
