Every dog is different. My girls learned to do the stairs by the time they were 8 weeks old, yet my boy, Phantom, was very timid and afraid. Everyone said "Give it time, he'll eventually learn". He is now 6 years old, and he still waits for me to carry him down
. My big baby
. I never pushed him, and honestly it doesn't bother me at all. The funny thing is, this big guy has no other fears - he will jump four feet high like it's nothing, and he'll run up the stairs so fast, but he won't come down. I had him from birth, so I know that he never fell, and nothing has ever happened to him around the stairs to frighten him, it's just one of those unexplainable things. By the way, we have carpet on our stairs.
