Start training her now on how to use steps or ramps. My yorkie is not allowed to jump down from the bed or certain couches that are two high. I have steps for the bed and several steps for my couches.
To train them to use the steps, I just put their favorite treat on each step. I repeated this until she understood it. Whenever I saw them jumping up or down. I just make them go up or down the right way by placing them on the steps and telling them to go up or down. Problem solved. I think the hardest part is getting them to not react so quickly when they want to jump down especially if they want to follow mommy. So be mindful that they will forget from time to time.
As for pooping on the potty pad, with my yorkie it is hit or miss. I am happy if she is only within inches. I really only have this problem in the winter time when we don't go out as much. She usually poops outside but in the winter time, mommy doesn't take her out as much. She's batting a hundred when it comes to peeing on the potty pad but pooping, she usually misses the target but at least she is in the vicinity of the potty pad
. I have natural's miracle and her poop is really small (thankfully) so for me it's no big deal. After having pets all of my life, I guess it's one of those things I learn to live with. Strangely she never poops when I am at home to correct her behavior. It's almost like she knows to wait until I am not around to poop just inches away from the potty pad or maybe she doesn't want to poop where she pottys'??? Who knows with these little stinkers.
