Oh nicola, I'm so very sorry to hear this. Throughout this whole ordeal you've handled it with such strength but I know how devestated you must be. It's clear how much your dogs mean to you and you must be heartbroken. It,s not fair but if this is the outcome then enjoy ever minute of your time with tilly. I have everything crossed for you both, that she does respond to this last round of treatment. Take care of yourself and tilly.
