I went to the basement to get something from the refrigerator and all of the dogs followed me down. Mike was upstairs in his office and Bones was following me for some reason. Since he is blind now he frequently confuses me with Mike and will follow me till he gets close enough to smell me at which point he just turns around and leaves. Anyhow, I came upstairs and was in my office when I heard the sound of something falling. I thought Mike had tripped and fallen down the stairs but Mike was upstairs clicking away at his keyboard. I looked down the stairs to the basement and bones was laying at the landing in the middle of the stairs. He was awake and trying to get up. I called for Mike and he came and helped Bones up the stairs. Bones seemed OK, but was unsteady.
