My 5 month siberian husky has b een diagnosed with renal failure and is in pain. how can i help her?

MY 5 MONTH OLD PUP WAS DIAGNOSED YESTERDAY: SHE IS ANAEMIC, VERY HIGH % OF URINE IN HER BLOOD AND HAS LOST LOTS OF WEIGHT, IS LETHARGIC, VERY WITHDRAWN AND FREQUENTLY CRIES IN PAIN. IT IS HEARTBREAKING TO SEE HER THIS WAY. SHE IS NOW ON A WHITE FISH DIET WITH A POWDER ADDITIVE TO FLUSH TOXINS OUT OF HER BLOOD. IS THERE ANYTHING I CAN DO TO EASE HER PAIN
