Cool toy. Fun for all
Color: Blue
A cool toy. entertainment for the dogs but more so for the dog parents to watch the dogs reaction. Comes with an additional rope just in case, which I loved. Only side note I would say is that the fast mood could be a little faster. My Golden retriever figured out the speed in less than 24 hours and now picks up the toy to try to chew it up, instead of chasing. With him attempting to chew on the toy in the small time I give him, there are no teeth marks yet…this toy appears to be durable. We play in short increments but enjoy the toy.

Must get!, Great interaction, mind stimulation
Color: Orange
Love this my pup can't get enough. My pup loves this and is hard on it. She throws it all around chases it and guards it like it is her child. It is strong, sturdy easy to charge and fun to watch her engage with it. Definitely must have and I will buy more. It shakes and rolls around, it walks itself and engages the pup to chase. The design is spectacular. It is light weight and the noise level is typical of a toy engaging response.

Awesome ball and made to last!
Color: Black & Yellow
Awesome ball! My dog loves it and plays with it all the time. He's a very aggressive chewer and there are only a few toys he can have without destroying them. Very pleased with this.

Pretty tough
Color: Black & Lake Blue
I think the toy is great, but my dog was not excited about it. He prefers the original type which is larger. I think it could possibly be cracked open by a dog with a large mouth and is intent on getting the noise maker out. But it is pretty tough.
