My Miniature Schnauzer was housetrained when we got her. She was really good about going to the door when she needed to go out to the bathroom. Lately she's been pooping and peeing in different areas of the house. I don't understand it because I take her out every couple of hours. It's driving me crazy and making my fiance' very angry. We shut her out of the bedroom sometimes when were eating and stuff because she stares and begs. I think she began doing it out of spite for getting locked out, but now it's getting out of control and happening more and more often. PLEASE HELP! Any ideas why she might being doing this? Any solutions? Thank you.
