I have a pregnant doe who has been coughing for the last month or two. The coughing is usually 3-5 coughs and comes at random times (not due to running) usually several times a day. I would not say it is very frequent but I can usually notice her coughing 1-3 times throughout the day when I am outside working around the area. Rarely, it turns into a coughing fit for up to about 10 coughs or so. Aside from the coughing her behavior is normal. It is also very dry and dusty here in southern Arizona right now and I considered that as a factor, yet the other does don't exhibit the same behavior. I have all but decided it is most likely lungworm; I can't seem to come up with anything else on my own and would like some help diagnosing this if possible. I am also concerned about treatment at this point because she is due March 1st and will be her first time kidding; and if it is lungworm will that pass to her kid(s)?
