Fun toy
Color: Orange
Well made. The puppies love it, BUT it is too hard for them at an early age ( 2 1/2 months. They ended up grabbing the rope. As they got 5-6 months they were fine. Make another model 1 inch smaller and half as hard Belgian Malinois & Doberman.

Durable & great deal
Color: Orange and Yellow
My foster German Shepherd has a jaw that's locked and loaded but love these cause I can play tug of war or fling it way across the yard. He's chewed or busted every ball he's received except these. I'm loving them. Very durable, bounces too really well and I can find it easily with the colors.

Small balls and came apart
Color: Orange and Yellow
My dog loves them; these are my first set of this type of toy. Good quality materials, but the knot in the rope came undone and the ball came off in 3days. I had someone fix and re-tie and it has held up so far. The next set I’ll get in a larger size, they’re a tad small for my dog’s mouth.
