Yorkies ARE very hard to train. I was having a problem with my little boy who is 2 and 1/2 years of age. (Remember they have such small bladders and experts say they can hold it in up to 8 hours...but really how should they know?) I finally gave up on mine. I went to the alternate, and put diapers on mine. I get regular baby diapers and use a boy band around the mid section, females can use under garments for dogs in heat located at any pet store. (Also Ebay has cute little panties and boy bands.)
putting a diaper on will save your carpet, and after a few months of my guy wearing a diaper, he learned to go out side. (He didn't like the pee feeling in his diaper.) Hope this will help you =)
