I have three female pitbull mixes. Two are sisters, last one is an adopted dog. I have noticed that my biggest female (Rogue) pees on any blanket or bed we put down for the adopted (Morgan). Really Rogue seems to pee on any fabric on the floor . we picked up Morgans blanket so the poor girl started sleeping on the rig and I just found that peed on. I have no clue what to do. They go out multiple times a day, And I have only caught her doing it once so I know it's her but I don't know how to correct it!
