Our young Hovawart dog would not fetch quite. So I tried to use his gluttony and nachzuhelfen a Futterdummie: The Dummie thrown for the first time. Dog runs, bringing the Dummie, gets his Gutti. The Dummie thrown for the second time. Dog runs, taking the Dummie, ran into the garden, plucks the zipper on and gets his reward out himself. My conclusion: probably ok for simply structured dogs, not suitable for our Hovi.
