Great toy!
Size: Small Size
My Frenchie absolutely loves this toy!!! It keeps her occupied for a long time. Has held up well to her chewing, and she's able to pick it up and carry it.

Great toy for small dogs
Size: Small Size
Our dog, who weighs 13 lbs, loves this ball. I like the fact that there are no batteries involved. The furry exterior is great for her as she can pick the ball up with her small mouth. I'd recommend this toy be used under supervision as larger dogs and heavy chewers could tear it apart quickly.

Not as soft as it looks
It’s like a hard ball with fur covering. My dogs want to play with it, but have a hard time picking it up. Sounds cool, tho! I wish it was more like a stuffed ball they could easily pick up and throw around
