Abby is now 10 months old. She was doing pretty well with potty training. An occasional accident in the house, but not often. We don't use her crate often, but I do put her in there occasionally just to keep her used to it. It's in the LR and always open. She has now decided that's her spot to pee. I just walked into the LR & she's done it again! I just had her out to potty 15 minutes ago and she did nothing. Came in, went into her crated & peed. I remove the tray & disinfect it each time, then spray it with Nature's Miracle to remove the odor. If she's in the crate for a period of time, she doesn't potty in there. And she never goes into Kallie's crate & pees. What would make her start doing this all of a sudden? And more importantly - how do I stop it?
