I have an 8 yr old border collie with an injured rear hock, so she can't chase the Frisbee any longer. This toy, when set on high, kicks her hunting instincts in, and she chases it, brings it back, and keeps it between her paws until it activates *or she bumps it). The plastic 'holey' covering let's her get a good grip on it, and it is a little larger than a baseball. Good quality plastic/soft rubber covering. It charges quickly, and has unpredictable jumps and rolls unlike some others that just run on 1 track. She would play with it all day if I let her. She brings it to me to play with her, but it doesn't really need a human's intervention. A tooth will occasionally hit the small control and turn it off, but no concerns about it falling apart or her ripping it apart. Highly recomment

Not as durable as it could be, but fun

Color: Yellow

Our 55 lb lab has fun with this toy, but it's not lasting long. The ball itself is hard plastic and the yellow rubber wrap around it has already been chewed through n several places. It did come with a fabric cover, but that, too, is not durable. Would not recommend leaving with your dog unattended as they could eat the rubber off in no time. But to bring out occasionally while watching the dog, which is what we do, it does provide some fun for all!
