We thought Bailey was potty trained, but recently she has had a lot of accidents in the house....nothing out of the ordinary has changed...we take her out alot to the yard and she is only allowed on the main floor, we try to montitor her as much as possible but she still has a lot of accidents...we crate her at night and the second she gets out of the crate we take her out...if we are not in the house she is crated...any suggestions?
