I will start by saying that Maggie is fine. So don't worry about the subject line. This will be way too long, but it has been growing for awhile. My brother who lived in Texas became ill (strokes, diabetes, old) and after staying with him in Texas hospitals for five weeks (leaving my husband and Maggie alone and missing them) I brought him here to Florida on a charter medical flight. My wonderful daughter and her husband drove his dog, bird, and all his important personal belongings 2,000 miles to be with him. He lived in our guest cottage with 24 hour a day nursing care along with his beloved dog and conure, Daisy and Popeye, and then to a facility when he could no longer live here safely. He passed away January 20th. I miss him a lot as he was my only sibling and we were close growing up. I promised him I would keep Daisy and Popeye and make them part of our family. Well, we brought Daisy into our home and all went fairly well for 3 weeks. Then Daisy decided she should be Queen and attacked Maggie. Hindsight being 20/20, we should have seen it coming, but we didn't. Actually, while Daisy initiated the attack, Maggie was the only one who drew blood. Daisy is almost 10 years old, a mixed breed )mainly black lab)dog my brother rescued when someone had dumped her in the pasture on a cold icy night. According to the vet, she was less than 8 weeks old. She was Queen of her home and, of course, Maggie is Queen of ours. My husband banished Daisy back to the guest house. We spend time with her daily(it is also my pottery studio again) and walk her a mile every day. Hubby softened and we decided to try again watching very closely and being more "Alpha" ourselves. My husband, Maggie and I all agreed that Maggie had to be Alpha in the dog family here, so we always greeted her first, fed her first, yada.... However, while Daisy was happy to be here and appeared accepting of the setup at first, she slowly began to attempt to dominate Maggie. Maggie weighs 74 and Daisy 62; however, Maggie is a "girly-girl" and Daisy is a survivor! We intervened at every point when she began to show any sign of attempting to dominate. However, after a few days, she became extremely pushy one night and I had to intervene about three times and I saw it was escalating, so I literally drug her out the door and put her on the back porch in "timeout". Well, I let her back in after about 20 minutes and she went straight for Maggie again. End of this attempt. Daisy is again living in the guest cottage. It isn't a bad life, but she seems so much happier with us. I now believe it is hopeless but wanted to get some feedback from this forum. I find the advice here is awesome. If this isn't something we can resolve, we will still keep Daisy and just have two dog homes, but we really wish there was a solution. I have read some online advice but it ranges from "watch out somebody is going to get killed" to "let them work it out". We clearly aren't going to let them work it out on their own. If we did, Daisy would be Queen and we just love Maggie too much for her to have to relinquish that position. Thanks for any ideas. I really appreciate this forum!
