I would just like to say that having read the last posts, I feel so sorry for you Hattie and can only imagine what you are going through.
We all get so attached to these dogs from day one, I think you are being very brave - first of all trying to get help for her and also admitting that it may be too much for you. The advice on this forum is fantastic, and has helped me a lot in the past. I hope Rosie gets the help she deserves, and I wish you well x
