Can't decide whether the horse is sneezing or coughing - i think it's a dust reaction (usually happens when her buddy is being groomed - gets very muddy so creates a lot of dust when brushed; and sometimes with hay). No problem when we are exercising. Anyway, i've tried cough mixture but not really doing anything - short of getting the vet to look at her (which i'll try to put off til after the christmas break now if i can) any ideas of what else to try her on?
