Oh Sue this is heartbreaking. That sweetheart has been through so much!!. When I read that he is still giving kisses, as sick as he is, it caused the tears to fall. Oh the love between dogs and their people just defies description, doesn't it. I hope your vet will be able to help and can give you encouragement to continue to hope and that Killi still has many good years ahead of him. I know you need our prayers too. Wish I was there to give you these in person. {{{{{HUGS}}}}}
