Haley's Comet in horse stall

Haley's Comet

Night Mare in pasture

Night Mare


Haley’s Comet stands in the stall and coughs. He has nasal mucus but no fever. When you clean the stable in the morning, he seems to have trouble breathing. When he’s eating hay, he coughs more. He also seems to be losing weight, and you can’t exercise him because of his labored breathing. “Oh no! The Kentucky Derby is in less than a month and we need to train . What shall we do?”

You decide to give him a rest and turn him out into the pasture. You notice that in a few days he’s running around the field with no hint of a cough.

However, Haley’s mother, Night Mare, stands in the field and coughs. She is turned out all year, but in the summer she has considerable trouble breathing as she grazes. When she goes on a trail ride, she can’t tolerate much exercise without showing signs of distress. You keep her in a stall for the weekend and call the veterinarian to schedule a checkup on Monday. By the time the vet examines her, she’s much better.
