Hi Aly, my thoughts after reading this mess is that the best thing you can do is get out of this situation, try to forget the people who hurt you, they will end up in a worse situation than you are eventually. I believe this is a power struggle by people who have no scruples.
If they did, the animals would be their first concern not the squabbling between themselves as to who would get a certain dog or not. Certainly they would want one of their own to adopt Spice and know that he would have a great home rather than sending him with someone they didn't know.
My personal opinion is that right now you should concentrate on yourself, look forward to your new job and not look back.
Of course Miss Daisy, Perry and myself wish you all the luck in the world in your new job and that right dog will come along when you least expect it. Remember Patience is a Virtue. lol
Jackie, Miss Daisy and Perry
