I bought this ball 6 months ago and feel obligated to come back all these months later to say how great it is! My Frenchie has killed every toy he’s ever had but not this ball! He absolutely loves this ball. It’s lightweight and can be used for both indoor and outdoor play and still looks brand new.

good ball, wrong color

Size: Medium

I think the hot-ee roller is a great ball! My problem is that there is no option to select a color. I thought I was getting a purple one, since that is what is shown in the picture. As usual, I failed to read that it was assorted colors. I have a peculiar little dog that will only play with the purple one. His current purple one is in tatters. You could hardly even call it a ball at this point. We have red, blue and green and they are invisible to him.
