my poor new baby is coughing we have her on antibiotics and in the barn(she also has a covered outdoor area) I was wondering if there was anything else I could give her to help the cough

Is she sick? (Runny nose, eyes, heavy breathing? ), do you notice when she coughs such as when you're feeding hay? I do always make sure I'm NOT feeding hay with any dust in it, makes mine cough and stop up quicker than any other horsey-food out there.
At Innissfree stables nearby, a girl has a pony who coughs alot. He is allergic to alfalfa hay (or something in it) but she feeds it to him anyway. He does better on pasture.

Someone else may have more ideas for you. I don't generally get those problems except for the above once in a great while.

I was going to ask a lot of the same questions AQHA did, is her temp normal? Is she acting totally normal other than the cough? How old is she?
Dusty hay is also a possible culprit. You might try soaking it in water for a few minutes before you give it to her.

I find dust alot more dangerous than mold (though I like to feed neither).

If your dealing with a sickness involve a vet.

If not, get mustatrd from the grocery store the kind in the squeeze bottle. Squeeze a good amount in her mouth, the same as you would a tube of wormer. If it's just a mild allergy,irritation, done 3 x, it should be completely clear.

Well, I learn something every day. Never heard of mustard.

It could be a number of things. Was she coughing when you got her? How old is she? Is she new to the area? Does her stall get plenty of air flow, and does it dry out from the urine? Does she have any drainage from eyes or nose? Is she running a fever? Is she eating and drinking okay? What antibiotics was she on, how long and how much? Did the vet perscribe them? Sorry so many questions.

If it is dust I would wet down her hay to get all the dust out, Make sure you use dust free type bedding.
If the stall is not drying out from the urine, the ammonia could be irritating the airways.

If the cough has been going on longer than a week and/or sounds like she is hacking up a lung, I would get in touch with your vet. Even though you may think the coughing isn't that bad it could be signs of something more serious going on. For Example.

One of my clients has a yearling stud colt, Who is in a nice open air barn, began coughing on and off 2 months ago she didn't think much of it till he had been doing it for a month and it became more regular and she noticed some nasal drainage. By the time she was said and done at the vet including chest xrays. She is now dealing with some very inflammed lungs and airways (mild to moderate case of COPD) and he is on 3 different type drugs that are not cheap. Some are inhaled and some are oral. He will be on these drugs on and off for at least the next 4-6 months. She now wishes that she would have had it looked at sooner.

It could be as simple as a dust type allergy or some more serious. It would be best to contact and talk with your vet.

Good Luck
