Yorkies should not be taught to potty in the crates even on a pad ,they do not like to potty where they sleep .
Does she have access to water all night?Perhaps picking up the water dish ...
I empty water bowls at 730 pm and only put an ice cube in the dish ,so they can have a little bit but not enough to fill their bladders .
also have a good 20 minute playtime before bed to help ensure a good night sleep
