Query: Keeps puppy busy

I bought this item for my 4 month old puppy. It only took him a few minutes to catch on and want it all to himself. The only problem was that he had trouble rolling it (with both his paws and nose). His paws would slide right off of the slick surface. I went to a local home improvement store and bought some non-skid tape (like you see on outdoor stairs...gritty like sandpaper, but a tape) and put some on all of the sides, except for the hole. Now he rolls it around without problems....that's the only issue with this toy. Otherwise, it's great!
