We have been doctoring a sick doe for about 3 weeks now. Believe it is Pneumonia. We have gone through 5 rounds of shots now, antibiotics, banamine, & poly-serum. She was breathing hard and lethargic. Also not eating. Her breathing seems better & sometimes eating leaves, cookies & a few pellets. Seems to be getting enough to drink. She is still very lethargic though. Also has a white powder on her coat. She had some trouble giving birth but seemed fine afterward. We are new to the deer farming and just not sure what else to do or what else it might be. How long can pneumonia hang on and how many times should she be given the shots. Hate to have her suffering and don't know if we are just prolonging the inevitable.
