I've been rewarding and praising her for pooing on the pad and cleaning the poop right away. I've also been ignoring her when she poops outside.
My problem is Kimchee is so random about pooing. I'll wake up and see some poop on the pad. She does seem to like to poop on the opposite end of the pad where she previously pee'd. Then she'll whine and go crazy so I take her outside because I think she has a lot of pent up energy. Then she'll poop outside! A few hours later she'll just be hanging out in her x-pen and she'll poop on the pad no problem!
I guess I'll just keep doing what I'm doing and hopefully she'll get it one day. Or maybe when it gets to be winter she'll resent pooing in the cold! On the bright side, she is about 99% with peeing on the pads!
How long did it take your puppies to master indoor potty?
