Welcome! Thank you for taking her in and doing what you can to help her. Your hearts in the right place, and this is the forum for you! If your current dog is not dog friendly, I would suggest a crate/rotate. There are threads in the training section you need to check out. Start with the "2 weeks, give em a break!" Then look for crate and rotate, as well as crate training. Many of us here have multiple dog homes, and do crate rotation. It's something you will get the hang of after a schedule is in place, and it works great for us. If you do not wish to keep her, but rather find her a home, you can have her spayed, shots, etc, then post an adoptable ad for her in the adoptable section. We do not allow rehoming of personal pets here, but we do allow homing of rescues. I hope you enjoy it here and we can help you out with your current situation.
PS... I LOVE Bull Mastiffs! Can we get pics?
