Yorkies can be so stubborn with housetraining. With my last male I used the clicker method. Of course I crate him during the day while at work, come at lunch to let him and out again after work. As soon as he would pee or poop outside he would get 2 clicks and immediately be given a small treat. He caught on pretty quick. You have to start out with just getting them use to the clicker, by just clicking and giving treats so that they will associate the clicks with positive behavior. Have not any accidents in the house for about 4 months and he is almost a year old now (fingers crossed)
