My dogs don't like this toy - THEY LOVE THIS TOY !!!!! It can be dangerous to your knees if you attempt to walk near them while they play with this. They grab one end of the rope and shake it like a pillow. I don't mean they just jerk it around they shake it like crazy - it makes me laugh when I watch them. When they are through shaking they lay it down and chomp the rubber ball and then go after the rope again.
