Keeps dogs busy.
Color: Orange
The dogs love this ball. They are afraid when it vibrates but as soon as it jumps and moves around, they are on it. They will play with it for quite awhile. Charge lasts for a long time. Very durable. This dog can tear anything apart but it's still in one piece.

Good for smaller jawed dogs.
Color: Orange
This ball is so much fun for our 5 month old. He both chases it and lets it bounce in his mouth. This was after playing with it already for 10 minutes. The ball charges with a usb charger and lasts for a long time. I do take it away to keep the toy fresh and prevent him from just chewing on it. I will say the ball startles you a bit when it turns on in your hand. Happy with a different toy.

Extremely durable, highly recommended!!
Color: Orange
This ball was a game changer for us!! I rehomed an extremely needy 110 pound one and a half year-old male Rott. This ball has been keeping him engaged for hours giving a much-needed break to me.😜 it actually stays charged a lot longer than I thought it would, and so far he is not chewed through it at all, which is incredible to me!! I think I’m gonna order another one so that I can have one charging while he plays with one and then switch off with them.

A hit for Border Collies
Color: Blue
Our border collie loves this toy! Keeps him entertained and when he throws it down it doesn't break open. Going strong for a couple days so far.
