The larger size stops a possible choking hazard for your full-sized pal.
Colors May Vary.
I had this for two minutes before it,was utterly destroyed i feel your name is false advertisement it should be called weak balls. I was very dissapointed
My dog is a medium size medium chewer and the ball has held up great, but she did take off the fuzzy stuff right away. She is still playing with it all the time. ;-)
"not so tuff"
This ball split open the first evening my dog played with it. It did not hold up as well as the cheap tennis balls I had purchased. I was very disappointed. My dog is a 55-pound Lab cross, so not an unusually agressive chewer.
