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. This ball is a little firmer than others of these I have had in the past, which helps exercise his giant jaw. I could get a few weeks out of the other brands I have bought. This brand is still like new well past the time others have failed. I will be ordering more as my French Mastiff is interested in one of his own (the boys do not like to share toys - most dog guardians understand).

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.
