Comments about My Good Dog 3" Vibram Ball with Rope - Camo 3" CAMO":
We have 2, 1 & 1/2 year old golden retrievers.
The vibram balls are great-very durable. Our dogs chew up tennis balls almost as soon as we give them to them. They haven't been able to chew up the vibram balls. They have however, been able to untie one end of the knot in the rope which allows the ball to come off the rope. That would be an improvement if there was a better solution.
