A picture is worth a thousand words applies to this product, as you will see in the attached photos these stand up to the abuse of a Great Dane. He has dragged me around the yard for hours already with this in his mouth and the stretchy handle keeps it shape.

Holding up well.

Pattern Name: Checkered

Seems to be holding up to my aggressive chewer. I have it hanging from a tree branch and she loves leaping to get it! Buying another pair so she has a greater selection around the backyard.
