Do any of you use the yorkie panties to help potty train? My two are 3 and 2 1/2 years old and maybe 90% housebroke. They have never liked (and very seldom) used the peddle pads. When I take them outside they almost alway go but once in a while I will find a surprise hidden in the corner. I was thinking about putting the panties on them while in the house and taking them off when we go outside. I was hoping in the end to train them to use the peddle pads inside and also go outside. Like today it is raining out so I wish they would use the peddle pads. Also, where do you buy the yorkie panties? Thanks,
