Heifer has pneumonia for about 3 weeks now, she's got a 4 month old calf on her, body condition is pretty poor. She got 3 shots of Nuflor as directed by the vet I'd say 2 weeks ago. She was on the mend after the shots, no discharge, breathing much better. We just checked the cows and she is bleeding from her nose with labored breathing again. Not a bloody discharge, bleeding. Suggestions?
