This is Bella. Bella was butten by a snake. Most likely a Puff-adder. This causes marked tissue swelling and necrosis (cell death) as well as bleeding. If enough serum was been injected by the snake it is often fatal.
She was lucky owing to her size and the venom dose was less than lethal. Homeopathy and fluid therapy was all that was needed to get her to full recovery. She did not require the very expensive snake abtiserum which often causes allergic or anaphylactic reactions.
