Hi! We recently rescued a 4 1/2 year old female English Bulldog. Based on what we have discovered, she was part of a puppy mill that was shut down. She was left outside, minimal human contact and absolutely no training. We have been successful in teaching her the basics, with the help of our 4 other furbabies but we are struggling with housebreaking. She goes outside multiple times, with the others, 7 times out of 10 she will not go potty. Even if she does, as soon as she is left unattended or at bedtime, she will potty on the floor. I understand that they are notorious for "taking their time" when they go outside but we are seeking help in getting thru this last hurdle so that we don't have messes every morning or whenever we return home. Any help/suggestions would be greatly appreciated. She might be a bit of a challenge but we just adore her and she knows it. Thank you in advance.
