What @SBMF 2015 said. Take her temp; normal is 101.5. If I suspect pneumonia, I look for coughing, snotty nose, watery eyes, droopy ear(s), not eating/drinking right, generally a little separated from the herd, trouble breathing. Foam is never a good thing. Will absolutely need a RX for appropriate antibiotics if your friend doesn't already have something specifically for respiratory like Draxxin, Resflor Gold, Nuflor, Baytril, Zuprevo, etc.
