Our KS is indoor pad trained. We used the Potty Training Puppy Apartment system and she did very well learning with it. It was a bigger purchase, but definitely worth the money for us. I no longer buy the pads from their website (
www.modernpuppies.com). I buy them at Tractor Supply. When she was getting the hang of it, I would praise her every time I could with a small treat. She caught on quickly. Good luck to you!
