Each dog behaves differently and so you can safely make any serous general recommendation or advise with sound results thereof. So I give only from a review. The sheep looks humanly yes cute. From dog run, this is to be regarded more sober and the interest of our Berner Sennenmix was primarily the eyes. The right held exactly 30 seconds stand, then gave up and found himself a few seconds later probably in Balou's stomach again. The rest of the sheep then held no longer than until the next afternoon before the seams gave way and the "guts" were visible. So ended the sweet sheep after 22 hours in the bin. Too bad! Möööh!
