I'm so sorry, my 9 year old Pup almost lost his life in November. He was overrun with Mites. The Vet, the holistic Vet didn't catch what was his problem. Thank goodness I had bad itching, that gave us the appropriate diagnosis. While he was being treated his heart became so weak. I can feel your despair, he was hardly breathing...but it wasn't his time. He is so healthy again. Love our furry babies...your sweet dog has been blessed with a good life with your family. I'm Praying for a miracle.
