Winter Coughs - Not a Good Wheeze!

Respiratory infections may also be involved - in particular, viruses such as influenza, and equine herpes virus. If an infectious disease is suspected, swabs can be taken from the nose to try to identify the organism responsible. Blood samples may contain antibodies to the offending virus.
In persistent cases it may be necessary to collect a sample of fluid from the airways. This is usually done using a flexible endoscope.
Although medicines can be used to help clear the horse's chest and reduce the inflammation, the most important factor in treatment is allowing the horse to breathe clean fresh air.
So how can you prevent your winter schedule being disrupted by coughing? First of all, avoid feeding poor quality hay. Soaking it may help. The water damps down the dust and makes the spores swell. But it also washes the water-soluble nutrients out of the hay and so reduces the feeding value. (If there is any doubt about the hygienic quality of the hay, your veterinary surgeon or feed merchant may be able to have a sample tested to see if it is safe to feed.) Consider feeding haylage instead.
Let your horse have as much fresh air as possible by turning him out as much as the weather conditions allow. Make sure there is adequate ventilation in the stable or barn. Avoid the temptation to close the stable up, even in the coldest weather. Keep the bed as dust-free and clean as possible. Do not muck out the stable with your horse in it. Give the bedding time to settle - preferably an hour or more - before bringing the horse back inside.
Give your horse clean air to breathe, and hopefully you will both enjoy a cough-free winter.
