We only have a couple of steps to get up and down in and out of the house....living in a one story house. My parents live in a rancher too and have a full size basement. Tubs will bound up and down the stairs going in and out of the house, but his will not go up or down the stairs to the basement. I thought it was the fact that the sink that we give him a bath in is down there and he just doesn't want to get a bath, but once down there he will not go back up the stairs either. I can understand the going down factor, I think he will flip head over heals going down too, but I don't know why he won't go up them. He is over 50 lbs now and getting hard to carry up and down the stairs. I also have a trailblazer and have to pick him up to put him in the car when he goes places with us, which is a lot. At least I am working my muscles and getting a workout!
