With the housebreaking, I'd just say be consistent. Take her out like a puppy - when she wakes up and after she eats. Attach a command to it like "go potty" or whatever. You can use different or same commands for the two jobs. Say that whenever she starts to do her business and then start to say it when you want her to do it. You'll probably begin to see her pattern over time - just watch for clues like her looking around and sniffing, turning around in a small circle. If you keep her very close to you these first few weeks, you'll both learn very quickly! As for the leash, my Anatolian does that. She actually does it because she's so excited. Hard to know what is going on in your situation but it MIGHT be that the leash means good things, like a walk, and she's so excited that she rolls over. If she really doesn't like the leash, with time and learning that it means good things, not bad, she may end up like my Katie and roll over with excitement. Possibly give a treat with putting on the leash? Good luck with her! We need some pics!
