Hi Crystal,
It has been so great to discuss this here because I feel like I am gaining some perspective and getting some great advice...which I really needed. You are so sweet to offer to find her a "forever home".
We live just a bit north of Orlando in Seminole Woods Community which is between Geneva and Oviedo. We are pretty "in the country". We have six acres, so the house and cottage don't share a yard though both are fenced. I would love to find the perfect home for Daisy, but I still doubt anyone will want her. In addition to her need to dominate, she digs. She lived in West Texas and the ground is so hard there, she never dug out..though she did dig a shallow indention in a flower bed that was "her spot". My husband put a temporary fence around the guest house when my brother came so Daisy could go in and out as needed without leashing her. She promptly began digging herself a nice deep cave which was great fun for her here in sandy Florida and we just left it because she loved to lie in it and peek out. She must have felt like she had super-powers! Now, when I put her back in the guest cottage after the last incident with Maggie, she dug out under the fence and chased the deer until she could barely walk. I repaired the hole (probably not too well and my husband is out of town until tonight) and she promptly dug out again and chased deer. The deer are sort of our pets so they must think we have turned on them, too. Now I am walking her twice daily and keeping her inside the guest house until my husband can fix it tomorrow. He said he is going to lay wire fencing overground in the entire fenced area. He must be an angel because he is really NOT happy with Daisy though he is coming to believe that dogs have a pecking order and that maybe we can't change it very much, thus taking some of the blame off her and looking for solutions.
So, if you find someone nearby who would truly love a 10 year old dominating (very healthy) sand-kicking, lab/whatever cross, I am interested. Otherwise, we will make her life as happy as possible in the guest house. I can't help but love her, but not sure anyone else will. I don't see her ever returning to Maggie's domain. It has really made me appreciate how easy Maggie is to care for, manage, train and love. She is just a wonderful little "follower" who always tries to do the right thing except when she is too excited like when company comes. (Like I didn't think she was the "Cat's Meow" before!)
Thanks again to you and everyone for support!
