Hello,
Im sorry to hear about your mom. I think the best thing to do is to call Jenn, my office manager tomorrow and explain all of these. We have some resources available that might be able to help. I also think that you should start posting on Facebook and Nextdoor.com. Reach out to everyone you know.

Hello,
Thank you for giving this girl a chance. I guess I’m a little confused abo to how you manage the bathroom and what, if anything, she has had that has worked. I would start by calling everyone and anyone you can think of. Including the breeder. And start asking for resources to help. I also think this is a long and slow road in some cases so you really have to be prepared for that. And understand that each failure sets her back immensely. So I hope that you can find help. She is afraid. The only way to treat that is with time and patience and absolute dedication. There aren’t any tricks of fast cures here. Use everything you can to gain trust. Treats. Food. Anything. Some dogs will respond to other dogs. Some respond to men or women or no talking and just reassuring rewards. But it all takes time. I don’t know how you started out but I’m worried that it left you little negotiating room. We always start with an assessment. A leash walk. Understanding them. And train from there. It sounds like you need help. So please start calling. But please be vet upfront about only using positive reinforcement. It sounds like all of her previous experience might have been brute force and domination training which is part of the reason she already has trust issues. Also call a Great Dane rescue and see if they can help. I hope the others answer too.
