I have 4 does that cough. Not real bad only a few times a day it sounds dry. When they did this in the winter i thought it was from the hay but there still doing this. They where wormed this spring with cyection oral sheep drench. Was wounding if i should try to worm them with something different to see if they have the lung worms. I have ivermection cattle pour on i could give but is it safe to give orally? Maybe i should record one coughing. Not sure if i could put it on here though.
