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.

Good interactive toy that keeps even my poodle mix busy
Color: Blue
We have a poodle mix that easily gets bored with most toys, including the other interactive bouncy balls. This toy seems to keep him busy though and so far he has not destroyed it or grown bored of it. The only problem we have is keeping it charged because he seems to wear it out but it is not a problem to recharge it with the USB cable that is included. It is a little tricky screwing the toy back together after charging the battery but I am getting the hang of it. Once it is set to one of the play modes the ropes on top (that you need to put on) will start spinning back and forth and the toy gyrates around seeming like it is alive to our dog. The loves playing with it in all of the modes but I think he likes that faster modes better. It comes with an extra rope which was good because our raptor dog already ripped the first one apart. The price on this toy is relatively low compared to tother toys to I highly recommend this for anyone that has a dog who is bored with the typical play toys.

Great Enrichment Toy for Treats or Kibble!
Color: red
I love this toy—and so do my dogs! It’s perfect for daily enrichment and works great as a kibble feeder too. It holds a generous amount (about 3 cups), rolls smoothly, and keeps my dogs mentally engaged while they work for their food.
One of my favorite features is the adjustable treat holes. You can easily change the difficulty level, which makes it suitable for dogs of all sizes and skill levels. Whether you have a beginner or a more experienced puzzle solver, this toy adapts perfectly.
It’s well-made, easy to clean, and durable enough for everyday use. This has been a great addition to our routine and helps slow down eating while keeping my dogs entertained and stimulated. Highly recommend for anyone looking to add more enrichment to their dog’s day!

Doesn't break easily
Color: yellow/orange
This toy works really good. I bought it from my daughter's dog when they bring her over but it ended up the cat. Loved it and knows how to play with it. Better than the dog did. LOL
