How old is your little one and how big is she? Because even though you may have gotten a small crate/cage, you may still need to block off a part of it to make it smaller. She really should have very very little room in the crate.
Also, are you giving her free range of your home without watching her every move? Do you look away for a second or more? If so, then you really need to watch her every nano second as long as she is out. If you cannot supervise her then she needs to go back in the crate. You may have to do this for months and months until she finally "gets it".
You need to take her out every hour on the hour and you may have to do this for months and months before she finally "gets it".
potty training some of these yorkies will take until they are 6, 7, 8 or 9 months old or longer. You cannot let up for one second on the supervision until "light bulb" goes off in her little mind and she knows what you want.
Just because she runs and hides from you when she goes potty in the house, does not mean she understands that what she has done is wrong. All she understands is that you get mad and she does not understand why. That is why she runs and hides.
Perhaps you can tell us what you are doing, what your schedule is and maybe we can help you tweak it for you for optimum success.
