Great engaging toy for my border collie
Color: Blue
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!

Durable enough for my dog's tough play. She loves this interactive ball.
Color: Blue, Color: Blue
I love these interactive ball toys. My dog gets so excited and engaged with them. I went through 3 of them that my dog destroyed in a short time. They simply were not durable enough for her tough play. So far, we have had this one for a few weeks, it is holding up and withstands her chewing and rough play, and she loves it. It keeps her busy for a long time.

Great toy for old dogs
Color: Yellow
Great to bring a old dog back to his old self. Have a 10 yr old who has a little shoulder pain but needs a little light excitement. This did the trick, he paws it a little and enjoys moving it around. It can take his biteing without breaking.
Hopeing our small dog whos afraid of it will watch and get over her fear. She learns everything from him.

Updated: not worth it. Disappointed!
Color: Blue, Color: Blue
Update: since I wrote my first review, I have to revise it. My puppy has chewed through the rubber case that surrounds the ball mechanism. I literally watched her chew through two sections in under a minute. I had to take it away from her and she’s so upset. I’m disappointed as it was a great distraction toy. Now it’s trash.
Absolutely the best interactive dog toy. My 5 1/2 month old puppy loves this toy. It’s the perfect size for her. She rolls and chews on it happily. Unfortunately she also figured out how to remove the cover, the Velcro is not strong enough, but I’m fine with that. It kept her occupied for over 25 minutes after I gave it to her. It looks well made and additional extra ball cover was a surprise. It was worth the price. We live in an apartment and unfortunately when it’s turned it make a little noise on the tile floor, I just hope my downstairs neighbor doesn’t get upset.
