So I bought my mare a little under two years ago, and every spring, around mid March to late April she gets this cough. Its not terrible, and its only when I'm riding her, and she coughs maybe 5 times in a ride. I don't think its heaves because it only happens once a year. Is there any supplement that could help this, such as Cough Free? Should I have my vet confirm she has allergies before I go ahead with the supplement? I just want her to be more comfortable, and not pull me out of the tack when she throws her head down to cough! Any input is appreciated.
She hasn't started the coughing yet this year, but I wanted to see if there was anything preventative I could do.
