For about two years my mare has been coughing whenever we start to trot. She'll cough for one or two rounds. It kind of worries me, but my riding instructor just brushes it off and makes jokes saying "she has asthma! Hahah"
I'd really like to know why she coughs.
It doesn't matter if we're in the dusty indoor, or clear outdoor. It doesn't matter if it's wet or dry, warm or cold. She ALWAYS coughs.
She only coughs when it's our first transition into the trot.
