Hi! I'm new to Yorkie Talk and joined the site to seek help or assurance there isn't anything unusual about my puppy. She's actually a shorkie (yorkie/shih tzu mix) and just turned seven months. Up until now she's been the perfect puppy. She obeyed commands, learned tricks and took to her potty pads quite easily and basically was very well behaved. I can't take her out to use the potty as I'm in a condo and it's not realistic to take her outside continually.
All of a sudden she's acting like she's forgotten everything she's learned and is being quite defiant. I understand there is an "adolescent" phase and I'm hoping her attitude IS temporary? The worst is when I tell her to do a good potty on her pad while sitting there with her while she's ON the pad. She'll take two steps off the pad and pee on the carpet. I miss my good girl - is she coming back???? Thank you for anything you can share or any advice you can offer.
