We adopted a rescue bulldog that was a former momma at a puppy mill. She has made tremendous progress as far as socialization, but I am still struggling with one area of potty training. She will not potty randomly in the house when we are home. However, the problem is when we leave the house. We put her in the laundry room and she will potty on the floor in there - but only when left alone. She will potty in her crate - appears she lost all instinct to not "soil her den" when she was confined for so many years - so crate training is not an option. Currently I am leaving puppy pads in the laundry room when we are gone, but I would love to teach her to hold it until we return. Has anyone had success potty training a former mill dog?
