Although our dog - Westie - is already over 11 years old, he has already accepted the stairs after 2 attempts. Just great! Unfortunately, I had the thing then stand in the bedroom by the bed, and when he tried to shut down the stairs again, he is runtergeplumpst - in the dark he could not see anything of course. But in the living room there is a real relief for us, because it sometimes high- every 3 minutes or down want.
