Thanks to each and every one of you and your insight, help, and information. We have decided, especially after reading Gemp's post, that Sadie would not be the best fit here. We are sending $$$, and some things that the shelter needs, to help out their cause.
Please, don't take offense any one, that we're doing what's probably best for Sadie, and our home. We live in semi rural cottage country, and there are many people in and out of our home, yard, and neighbourhood on a daily basis. I do not know that I could handle, as Gempress says "VERY protective of our home and vehicles. I don't recommend a 'houla if you're not willing or able to handle a dog who will actively defend against trespassers". I truly wish that Sadie would be a better fit with our home, but I am glad I gave it some thought and asked the right people the right questions before bringing her here, and then having problems I am not ready to deal with.
I will find the dog for me, and Sadie already has people interested in her, where she'll probably be farm bound, with lots of llama's!
Thanks again everyone, I knew I could count on your "saner" input! I don't normally fall for the "eyes", but Sadie had my heart strings.
