Not every dog is the same, some just take longer. Lots of patience and praise, treats when she hits the mark. I was very successful in training all my pups, but it is said potty training yorkies takes a bit longer. She will get it, just be patient. Maybe making more of a fuss when Zeus gets it right, and NO fuss when Xena doesn't. Yorkies LOVE attention, happy dance, crazy praise, treats, maybe if she sees Zeus get all that and she gets none she may try harder. I am sure others will be along soon that had same problem and can tell you what worked for them.
