PUPPY APPROVES
Color: Orange
Fun interactive toy. I felt this was a little pricey but watching my puppy playing with it is priceless.
She flings it all over the room. As a puppy she chews on it a lot because of teething but there still isn’t a mark on it.
Battery lasts a very long time and requires no replacement batteries just a usb connection.
It is a little noisy so sometimes I let her play with it without turning it on.
All told, it is one of her favorite toys. She is 4 months and weighs 7 pounds, just to give you an idea if it will work for your dog.

Absolutely would buy again
Color: Orange
I love this, my pup loves this.
Strong, sturdy. Shakes all over the place.
Pup loves to chew on it, I think the vibration comforts her gums from teething.
Perfect size
You must take the outer skin off and pop open the white power button to charge it.
Total fun!

Rubber blue cover won't come off.
Color: Orange
If you want to keep the blue cover on that your dog chews off every other ball that is similar, get this one. Most dogs will not chew it off. It stretches when the chew on it so it can't be chewed or stretched off the ball. I've got a blind dog and she will kick it around for an hour at a time. It keeps her active and having fun.

Nice, but...
Color: Orange
It's a good idea & keeps my 1yr old Staffy/Pit occupied, BUT... The rubber around the ball is either too easy to chew through or my pup is just an aggressive chewer. Either way, it's a plus that it does come with an additional rubber, but it would be nice to also be able to buy additional ones vs having to buy the whole toy again & again! Oh, & if you think about letting them play with it without the rubber please be on the lookout for the rubber covering where you would charge it because my pup managed to locate & destroy that cover piece as well haha!
