It is small, like your friend. But, it is tough!
Tugger's Tiny Ring built with forestry fire hose, is an interactive tug and fetch toy, about 6 inches diameter, is built from "inch and a half" recycled fire hose. Squeakers are sewn into the toy in compartments. (So the toy will not be a"perfect circle".)
