Heading Key Points High Blowing and Fluttering Nostrils Indicate distress in horses; can be normal during intense exercise but concerning if persistent at rest. Causes of High Blowing Laryngeal Hemiplegia: Vocal fold paralysis, more common in Thoroughbreds. Dorsal Displacement of the Soft Palate: Can lead to snoring-like noises and intolerance to exercise. Epiglottic Entrapment: Can require surgical correction. Fluttering Nostrils and Respiratory Distress Indicates the horse is working hard to breathe due to constricted airways. Common Respiratory Issues Equine Asthma: Chronic airway inflammation, dust and mold are common triggers. Inflammatory Airway Disease: Excess mucus, persistent cough. Environmental Allergies: Pollen, dust, poor air quality. Performance and Health Impacts Respiratory issues can significantly hinder oxygen uptake, affecting performance and health. Prevention and Vet Consultation Soak hay, opt for low-dust bedding. Enhance ventilation. Consult vet if symptoms persist. Exploring the Causes and Significance of High Blowing and Fluttering Nostrils in Horses Horses, much like humans, can signal distress in unique ways. One of such indicators is through high blowing and fluttering nostrils. This article plunges into the reasons behind these nasal gymnastics and their implications, aiming to keep your equine friend in peak condition. What Do High Blowing and Fluttering Nostrils Look Like? Picture your horse mid-gallop: instead of the gentle sound of wind, there's a clear "high blowing"a series of puffing or whistling noises, often synchronized with their movements. This phenomenon is the result of nostril or false nostril vibration during exhalation. If your horse's nostrils are fluttering dramatically, they might be struggling for air, using all means to increase airflow. These sounds might be mundane during an intense workout but can signify deeper issues if persistent during rest or coupled with coughing or poor performance. Studies suggest that respiratory noises can lead to performance drops in up to 70% of affected racehorses [Horsetalk]. Common Causes of High Blowing in Horses Laryngeal Hemiplegia (Roaring) This condition sees one of the vocal folds paralyze, producing a "roaring" sound on inhalation. It's more common in Thoroughbreds but can affect various breeds, impacting up to 20-30% of racehorses over two years old [Kentucky Equine Research]. Dorsal Displacement of the Soft Palate The soft palate flipping up blocks air, creating snoring-like noises and exercise intolerance. Treatment ranges from rest and medication to surgical intervention in severe cases. This condition is prevalently seen in performance horses. Epiglottic Entrapment This is where cartilage traps the epiglottis, affecting airflow. Although it doesnt always hamper performance, surgical correction is often necessary. Fluttering Nostrils: Signs of Respiratory Distress Fluttering or flared nostrils is a red flag that your horse is working overtime to breathe, likely due to expiratory effort where air is trapped in constricted airways. A horse's normal resting respiratory rate is 8-15 breaths per minute, so noticeable increases accompanied by nostril flaring indicate stress [The Horse]. Equine Asthma (Heaves or RAO) This condition results in chronic airway inflammation, often causing mucus and spasms. Severe cases see nostril flaring at rest, with a characteristic "heave line" along the belly. This affects about 10-20% of stabled horses, with common triggers being dust and mold [Equine Guelph]. Inflammatory Airway Disease (IAD) This subtle condition strikes performance horses, manifesting as excess mucus and a persistent cough, though nostril fluttering might only appear during strenuous activity. Environmental Allergies or Irritants Things like pollen, dust, or poor air quality in barns can provoke watery discharge and nostril flaring. Dusty stalls present prime conditions for such irritants [Alberta Equestrian Federation]. Why These Signs Matter: Performance and Health Impacts The implications of these signs go beyond mere annoyancethey severely hinder oxygen uptake and, by extension, performance. Airway noise can curtail exercise efficacy, and obstructions can lead to a 10-20% drop in speed according to studies [Horsetalk]. Real-World Facts and Figures Respiratory issues often overshadow lameness in performance horses, with half of all horses experiencing asthma at some point. Dust from inadequate bedding is responsible for over 80% of heaves flare-ups, illustrating the direct correlation between environment quality and respiratory health [Kentucky Equine Research]. When to Call the Vet and Prevention Tips It's time to summon a vet when high blowing persists after exercise, nostrils flutter at rest, or there's noticeable coughing or discharge. Early interventions are key to preserving your horses long-term health. Meanwhile, prevention can be your first line of defense: Soak hay and opt for low-dust bedding to slash irritants by up to 90%. Enhance ventilationgood airflow dramatically reduces asthma risks. Keep an eye during workouts: a bit of puffing is fine, but roaring or labored breathing isn't.
