Oh, Liz, I'm so sorry that you have to be thinking of this. I, too, know that I may have to think about it in the near future. ( They say that 2 yrs. with liver disease is an average. Killi was diagnosed last year.) You will know when the time comes. It will be the hardest thing you have to do for the one you love so much, but it will be something you MUST do for Bud's sake. I hope that you still have a long, long time with Bud. I'm praying that the meds and the nice weather will give him relief. We're here if you need us. Our hearts are with you!!
