Sue, I'm in tears for you. I'm so very sorry. I remember "meeting" Shiloh and Killi as some of the first PT dogs I saw on here. I know how very special the both of them are to you. It's too bad that we have to say goodbye to such wonderful beings.
I really hope this isn't the case, and that Shilioh will be with you for a while to come.
{{HUGS}} to you both and I hope for a miracle. Please keep us updated. {{{{{{{{{{{{{HUGSS}}}}}}}}}}}}
