I am very sorry this happened to you Gempress. A similar thing happened to me once when I adopted a female from the pound (this was before Benji). We think she was a Malinios mix, and Mals are VERY drivey, which she was. She attacked Daisy, causing Daisy to to need a bunch of stitches in her ear. We had to bring her back to the pound and she ended up in rescue, where she still is. The difference was, though, that Minnie (what we named the Mal mix) was consumed with hatred for Daisy after that attack and wanted to get her if she saw her. Daisy was terrified.
You describe your dogs as being happy to see each other. Maybe a behaviorist could help? Because it is VERY hard to find somebody who wants to adopt a DA dog. We have DA dogs at our rescue that have ABSOLUTELY NOTHING wrong with them except that they need a home without other animals. They are sweet, loveable dogs that have been with us for over a YEAR. Getting Voodoo a home in a few days would be nothing short of miracle. Although, Chaz HAS pulled some off before.
I just wish you luck!
