Which condition does NOT typically require urgent medical intervention in horses?

Chronic Obstructive Pulmonary Disease (COPD), also known as heaves, is a chronic respiratory condition often seen in horses, particularly those exposed to dusty environments or certain allergens. Unlike acute emergencies such as cyanide toxicity or gastrointestinal emergencies like gastric-dilatation-volvulus and intestinal intussusception, COPD is generally managed over a longer period.

In cases of COPD, management includes reducing exposure to irritants, providing appropriate medications, and adjusting the horse's environment. While COPD can certainly flare up and lead to respiratory distress, it does not typically constitute an immediate life-threatening situation that requires urgent intervention compared to the other listed conditions, which can lead to rapid deterioration if not addressed promptly.

This distinction emphasizes why COPD is not considered an urgent medical condition: it is a manageable, chronic issue rather than an acute crisis requiring immediate care.
