I really appreciate everyone's posts and opinions. No, I haven't made up my mind yet. I was in a bad accident 7 weeks ago and am still recovering, and haven't given much thought to anything else but healing.
Also, I wouldn't base my decision on one poster's bad experience (although I appreciate the post and realize that there are good and bad vets on both sides of the pond). Mandy saw 3 vets in the US before we got a diagnosis for her heart condition (or more accurately, a solution/effecitve course of treatment).
And although my ex would take her, he wouldn't put out any extra money for her (like paying someone to sit with her during the day or play with her, etc.) He also would be lax in taking her to the vet, since he's hardly home and wouldn't recognize early signals of her being sick or in distress. I have no other family that would take her. She's at that 'problem' stage of life where it would take a lot of love and commitment for someone to put up with her many ailments.
I look at her sweet face and think I couldn't possibly leave her, but I still just don't know. *sigh* I think as soon as I am feeling up to it, I will start her on the pet scheme requirements and play it by ear for the next few months. At least then I will be making arrangements for her to come with me if that is what I decide to do.
Thank you again everyone.
