Do not waste your money
Color: Large size (ø 7.4")
Not for aggressive dogs. I thought this was good for the money it’s not. My dog chewed this up in less than a minute. Not too happy

It's A Beast - But It'll Last Forever
Color: Large size (ø 7.4")
This big orange interactive dog toy does a few things differently—and mostly, it does them right.
First, there are no batteries and no charging required. The internal noise maker is activated by movement, producing little squeaks and quacks that grab a dog’s attention without turning into an electronic science experiment. Second—and more importantly—this thing is built to last. It’s designed to work as both a ball and a tug toy, which means it’s far tougher than the typical interactive balls that get shredded in short order. I fully expect this one to stick around for a long time.
That said, the reaction from my dogs was… mixed. All of them were a bit spooked at first. The sounds made them curious but cautious. My Border Collie was the first to commit and play with it, and she gave it a solid try. After a while, though, interest faded and the toy ended up sitting on the floor largely ignored.
I can get them engaged if I roll it around and hype things up, but the two dogs that usually love tug-of-war haven’t latched onto this one yet. My guess is this toy will shine more outdoors. Once spring rolls around and it’s flying across the yard instead of the living room floor, I suspect it’ll get a lot more action. My dogs tend to burn energy—and enthusiasm—much faster outside.
If you have a heavy chewer that destroys fragile interactive toys (and drains your wallet in the process), this is a very welcome alternative. Considering how quickly $35–$50 electronic balls can meet their end, this toy earns its place in the basket for durability alone.

Good for non chewers
Color: Large size (ø 7.4")
Dog lived it for the 4 minutes before he chewed a large hole in it. Definitely not for heavy chewers.

Terrible
Color: Medium size (ø 5.5")
Received 39 minutes ago. Chewed up in tiny pieces already. Feels like hard plastic in a cheap car.
