We've found the best toys are as big as she is: a gallon vinegar jug, plastic, with a shoestring tied on the handle. It is better than a milk jug because it rolls. I found a nylon harness in a drawer, never used because it was too small for Cur. The box says 'Large' but taken up as small as possible, it's almost a perfect fit. She thinks it makes her itch, and scratches at it with her hind foot.
