My goats have had a cough since some time last summer! Sometimes it's worse then other times but it's still there.They seem perfectly healthy other than the coughs. I have treated them with two rounds of antibiotics and i tried to just wait it out but they still have it! Sometimes they get a little diarrhea and a snotty nose with it. Does anyone know what to do? Im wanting to get some more goats but don't want them to get sick with it!
