Our puppy has a serious connection with this ball. We had one, lost it. I ordered another one a bigger size cause he had grown a lot. Well it was too big, he carries it everywhere so it got little red marks on his lips and ended up making a sore on the bridge of his nose. Luckily the hair has started to grow back and we have gotten another new ball the same size as the first. I am not sure I can accurately express his love for this ball. Also he will not share this ball, he won’t bring it back. Every other toy we play fetch with he brings back and if you don’t pay close enough attention he will nudge you with it. But not his Jolly ball. He may come close but only to sprint then other direction.
