this is my unprofessional opinion - and i'm sure others will have better advice, but....
that's something that really never, ever crossed my mind. when it came time to go up/down the stairs - i just went and my pup followed. she's only 8.8 pounds (not a yorkie though) at 4.5 months old.
i think they just learn to do it/know to do it - something. of course, i could be totally wrong - it's just my thoughts. |
