Dog overcame fear for stairs

Chance grew up at a one-floor place. It was a surprise to us that one year old Chance doesn’t know how to climb stairs. It took us for a while to train her to climb our backyard. We put foods on the top, Chance tried very hard, after fell and failed several ten times.... Eventually she made it! It is interesting that after many times climbing, every time facing the stairs she still hesitates...but we are so appreciate for her efforts.
