I have a goat that has had a dry hacky cough for about three months. He has bright pink lids and was wormed about 1 1/2 ago with cydectin. He eats and acts well, and really has grown in the last 6 months. He has had no nasal drainage. I especially notice it when it runs or after eating. Then over the past 2 weeks I have noticed my does on the other side of the fence (they are bred) have developed the same sounding cough. Is it just allergies? Is lungworm contagious and also what wormer is best to treat lungworm? All my goats eyes on the FAMACHA scale are pink to dark pink. Suggestions on what it could be and what to do. The reason I ask.... I want to sell my buck, plus I don't want to have future problems with my pregnant does. Thanks!
