I have a year old female yorkie named bella and she poddy trained herself at 6 months old. She used to go outside and do her business and have no accidents. She has been doing awesome until just 3 weeks ago. She started doing her business inside on our runner near the front door. We were gone for two weeks because we just got married so we had my mom watch her at the house while we were gone and she is very close to my yorkie. She also has a big dog companion at all times with her. And she didnt have any accidents until we got home.. so is this seperation anxiety and if so how do i break her from going poddy in the house??
