Helping your horse manage seasonal allergies requires a proactive and comprehensive approach. Identifying the specific allergens and implementing strategies to minimise their impact can significantly improve your horse’s comfort and well-being. Here are our tips and advice for helping your horse with seasonal allergies.

What are the symptoms of seasonal allergies in horses?

Seasonal allergies in horses can manifest in a variety of ways, primarily affecting either the respiratory system or the skin. This allergic response is often triggered by pollen, mould, or insect bites prevalent during the spring and summer months. Recognising these clinical signs early can help manage the condition and ensure the individual horse’s well-being. So, how can I tell if my horse has seasonal allergies? Here are some responses to allergens to watch out for:

Respiratory Symptoms

Horses suffering from seasonal allergies may exhibit a range of respiratory symptoms, similar to how humans react to pollen. These signs of allergies can include:

• Coughing: A persistent cough can be a reaction in horses that indicates irritation in the horse’s airways, often caused by pollen or other airborne allergens.
• Nasal Discharge: A runny nose, sometimes accompanied by a clear or slightly cloudy discharge, is a common sign of an allergic reaction in horses and an inflammatory response.
• Head Shaking: This may occur as the horse attempts to relieve irritation or discomfort caused by allergens affecting their nasal passages or eyes.
• Lethargy and Poor Performance: Allergies can lead to a general feeling of malaise, reducing the horse’s energy levels and affecting their ability to perform tasks.
• Lost Concentration and Behavioural Problems: Discomfort from allergies can make it difficult for horses to focus, leading to behavioural changes or irritability.

Dermatological Symptoms

In addition to respiratory issues, horses may also suffer from skin-related symptoms as a result of allergies:

• Sweet Itch is a severe allergic reaction to insect bites, particularly from midges, resulting in intense itching and discomfort. Horses with sweet itch (click to read our useful article on it) may rub or scratch excessively due to their insect bite allergies, leading to hair loss or skin damage.
• Eye Discharge: Allergens can cause the eyes to water, leading to a noticeable discharge that may require cleaning and care.

Can seasonal allergies in horses cause respiratory issues?

Yes, seasonal allergies in horses can indeed lead to respiratory issues, often mirroring the symptoms seen in humans who suffer from hay fever or other pollen-related allergies. Horses, with their robust respiratory systems, rely heavily on the integrity of their airways to maintain optimal health and performance. However, when exposed to allergens prevalent during certain times of the year, most commonly from April to September, respiratory allergies can cause this delicate system to become compromised.

Can horses have hay fever or pollen allergies? How to help horses with hay fever?

Like humans, horses can indeed suffer from hay fever or pollen allergies. These conditions are typically seasonal and occur when horses have an exaggerated immune response to inhaled allergens such as tree, grass, and weed pollens. Common symptoms of pollen allergies in horses include coughing, nasal discharge, runny nose, and watery eyes. In some cases, horses may also experience respiratory issues similar to human asthma, known as Equine Asthma Syndrome. This can manifest as laboured breathing, wheezing, and poor performance, particularly during high pollen seasons. Take note that there is growing evidence that Magnesium may have a role in managing asthma through its dual effect as an anti-inflammatory and bronchodilating agent (it inhibits the effect of Calcium to contract smooth muscle of the airways). Be aware that Magnesium Glycinate provides the highest levels of absorption and bioavailability (more than Magnesium Citrate and way more than Magnesium Choloride).

How to Help Horses with Hay Fever

Managing hay fever or pollen allergies in horses in the warmer months requires a strategic approach to minimise exposure to allergens and manage symptoms effectively. Here are some practical tips to help alleviate your horse’s discomfort during allergy season:

1. Monitor Pollen Counts: Utilise smartphone apps or online resources to stay informed about pollen levels in your area. Plan your horse’s outdoor activities accordingly, avoiding high-pollen times and locations.
2. Stable Management: Ensure your horse’s stable environment is as dust-free as possible. Use dust-extracted bedding to prevent additional irritation to their respiratory system and skin. Avoid storing hay and feed in dusty conditions and consider wetting them before feeding to reduce airborne particles.
3. Water Accessibility: Always provide fresh water for your horse, and avoid placing water buckets under trees or areas with high pollen concentrations. This will prevent pollen from contaminating their drinking water.
4. Outdoor Exposure: Limit your horse’s time outdoors during peak pollen hours, typically early morning and dusk. If possible, graze them in areas with low pollen exposure and keep the grass shorter to reduce pollen presence.
5. Protective Gear: Consider using fly masks and fly sheets designed to shield your horse from allergens when they are outside. These can help decrease direct contact with pollens and biting insects.
6. Medical Intervention: If symptoms persist, consult a veterinarian for a thorough examination to rule out other conditions. Creating a treatment plan will help. Prescription medications, such as corticosteroids and bronchodilators, may be necessary to control inflammation and maintain open airways during severe episodes.
7. Supplements: As part of your horse’s management program, consider respiratory supplements that support lung function and overall respiratory health.

By implementing these strategies, you’ll be better equipped to help your horse navigate the challenges of pollen allergies and ensure their well-being and comfort throughout the allergy season.

How do you treat seasonal allergies in horses naturally?

Treating seasonal allergies in horses naturally involves a multifaceted approach that focuses on reducing exposure to allergens, supporting the immune system, and utilising alternative therapies known for their beneficial effects. While severe allergic reactions may require conventional veterinary interventions, natural treatments can be highly effective for managing mild to moderate symptoms and enhancing the overall well-being of horses.

Do horses have allergies to dust or mold?

Yes, horses can indeed suffer from allergies to both dust and mold, which are common environmental allergens found in stable and pasture settings. These allergies can significantly impact a horse’s health and well-being, primarily affecting their respiratory system and skin.

Dust Allergies in Horses

Dust is a prevalent allergen in a horse’s environment, often originating from hay, bedding, or the general stable atmosphere. When horses inhale dust particles, it can lead to respiratory issues such as coughing, wheezing, and nasal discharge. Additionally, dust can contact the horse’s skin, causing skin irritation, hives, or rashes. To manage dust allergies, it is crucial to maintain a clean and well-ventilated stable environment. Using dust-free bedding and providing high-quality, dust-free hay can help minimise exposure. Regularly cleaning and managing stable conditions are essential steps in reducing the risk of dust-related allergic reactions.

Mold Allergies in Horses

Mold spores present another significant allergen for horses, commonly found in hay, feed, or damp stable environments. Inhaling mould spores can irritate the horse’s respiratory system, leading to symptoms like coughing, wheezing, and nasal discharge. Mold can also cause skin conditions, resulting in irritation, hives, or rashes. To effectively manage mold allergies, it’s essential to store hay and feed in dry, well-ventilated areas and to utilise mold-resistant bedding. Keeping stables clean and moisture-free is also vital in preventing mould growth and reducing the risk of allergies.

Both dust and mold can be problematic allergens for horses, impacting their respiratory and skin health. By diligently managing their environment and ensuring stables are clean, dry, and well-ventilated, we, as horse owners, can help mitigate these allergy risks and promote better overall health for our equine friends.

Can a horse’s diet affect their allergies?

Yes. Store feeds in a dry area and use feed that produces less dust. Wetting their feed slightly can also prevent dust inhalation during meals. Consider adding supplements that support respiratory health and immunity, such as omega-3 fatty acids and vitamin C, and herbal products like spirulina.

A robust immune system can help your horse better tolerate allergens. Natural supplements like Aloeride can help and play a significant role in providing a buffer. Meaning something that ameliorates the reaction to a trigger. I have heard this feedback since 2004 from patients with Irritable Bowel Syndrome in which Aloeride placated or even prevented symptoms whenever a slip in dietary discretion happened. Of course that is in respect of dietary triggers, not airborne triggers… As I wrote in this article, food choice is easy for humans, feed choice is much more complicated for horse owners… But ingested aloe vera was found to help horses during equine influenza (In the September 2018 issue of Frontiers in Microbiology research was published that in vitro test revealed that aloe vera polysaccharides could inhibit the replication of a H1N1 subtype influenza virus) and, in that similar way, oral aloe vera in meaningful potency and dosage can provide a useful buffer for when allergens enter. Given that all allergic reactions involve mast cells and their release of histamine and other inflammatory mediators, feeds and supplements that reduce inflammation are to the benefit of your horse. One sachet a day and use the trial offer.

Incorporate herbs with anti-inflammatory and antihistamine properties, such as chamomile, nettle, and flaxseed to help reduce allergic reactions and soothe symptoms like skin irritation.

Supplementing your horse’s diet with omega-3 fatty acids can help reduce inflammation and support overall immune health. If your horse is under veterinarian care for allergy treatment.

Can horses have food allergies?

Yes, food allergies can occur in horses. With so many ingredients in horse feed, it can cause reactions in horses. Modern horse feeds may have a lot to answer for.

What are the best natural antihistamines for horses?

There are several natural antihistamines that could help manage your horse’s seasonal allergies by alleviating symptoms without the potential side effects associated with synthetic drugs. Here are a few to consider:

1. Quercetin

Quercetin is a naturally occurring flavonoid found in many fruits and vegetables, such as apples and onions. It is known for its powerful antioxidant and anti-inflammatory properties. Quercetin acts as a natural antihistamine by stabilising the cells that release histamine in the body, thus reducing the occurrence of allergic reactions. It can be given to horses as a supplement, but it’s important to ensure the dosage is correct, as advised by a veterinarian.

2. Bromelain

Bromelain is an enzyme extracted from pineapple stems and is often used in conjunction with quercetin to enhance its effects. It helps increase the absorption of quercetin in the body and has its own anti-inflammatory properties. It may help reduce respiratory distress and ease nasal congestion in horses. Bromelain is typically found in supplement form, designed specifically for equine use.

3. Nettle

Nettle has long been used as a natural antihistamine due to its ability to reduce histamine levels in the body. This herb can help manage allergy symptoms effectively by decreasing inflammation and calming the immune response. Nettle can be administered to horses in various forms, such as dried nettle leaves mixed into their feed, or in supplement form. It is considered safe for most horses but should be introduced gradually to monitor any adverse reactions. Always consult with a veterinarian before starting any new herbal remedy to ensure it complements your horse’s health needs.

How to adjust your horse’s environment to alleviate allergies

Changing your horse’s environment can significantly help in managing their seasonal allergies. How can I make my barn allergy-friendly for my horse? here are our tips;

• Improve Ventilation: Ensure that stables are well-ventilated to allow fresh air to circulate, reducing the presence of dust and allergens.
• Clean Regularly: Maintain a regular cleaning schedule for the barn to minimise dust, moulds, and other allergens.
• Opt For Dust-Free Bedding: What is the best bedding type for horses with allergies? Use dust-free bedding materials, such as rubber matting or low-dust straw, to prevent respiratory irritations.

Should I limit my horse’s exposure to pollen?

Yes, limiting your horse’s exposure to pollen will help elevate their symptoms. However, you need to know the exact pollen your horse is allergic to in order to help limit exposure. For example if your horse is allergic to tree pollen, you will want to ensure their field is away from trees. Here are some tips;

Keep Up Your Pasture Maintenance

• Rotational Grazing: To minimise exposure to allergens in specific areas and keep your horse healthy, implement a rotational grazing system. This allows certain pastures to rest and recover, reducing allergen load and maintaining healthier grasslands.
• Weed Control: Many weeds, such as ragweed or nettles, can be significant sources of allergens. Regularly inspect and remove these undesirable plants from your pastures. Consider using eco-friendly herbicides or manual removal to maintain a horse-safe environment
• Dust Management: Dust is a common allergen for horses. Wet down dusty areas or choose a location for the pasture with lower dust levels. Additionally, with horses with dust allergies, avoid overgrazing which can lead to bare, dusty patches in the pasture.
• Time of Day Grazing: Limit your horse’s grazing time during peak pollen season and avoid early morning and late afternoon. During these times, pollen levels in the air are highest and can trigger allergic reactions.
• Tree and Shrub Barriers: Planting natural barriers such as trees and shrubs around the pasture can help catch airborne allergens and provide a break from the wind, further reducing allergen exposure.
• Regular Re-seeding: Ensure your pastures are lush and healthy by regularly re-seeding with grasses that are low-allergen varieties. Choosing the right type of grass can make a significant difference in reducing the pollen and dust levels that affect your horse. Some grass types have fewer flowers and lower pollen production, making them a better choice for pastures used by horses with allergies. Additionally, maintaining a dense and healthy pasture by re-seeding can help prevent bare, dusty spots that can exacerbate respiratory issues.

Review Your Water Sources

• Fresh Water Availability: Ensure that your horse has constant access to fresh, clean water. Hydration helps maintain mucous membrane health, which can be crucial for minimising the impact of allergens.
• Reduce Contaminants: Regularly clean water troughs to prevent algae and bacteria build-up, reducing the risk of waterborne allergens. Consider using automatic waterers to maintain consistency and cleanliness.

What is the fastest way to fix seasonal allergies?

Addressing seasonal allergies in horses efficiently requires a multifaceted approach that combines minimising exposure to allergens with appropriate medical interventions. Here’s a step-by-step strategy to quickly alleviate your horse’s seasonal allergy symptoms:

1. Identify and Minimise Allergen Exposure

The fastest way to alleviate symptoms is to minimise the horse’s exposure to offending allergens. This involves:

• Stable Management: Horses with pollen allergies should be kept indoors during periods of high pollen counts, typically early in the morning and late in the evening. Similarly, if dust or mould is a concern, ensure the barn is well-ventilated and consider using low-dust bedding.
• Turnout Strategies: For insect-related allergies such as sweet itch, avoid turnout at dawn and dusk when biting insects are most active. Equip your horse with full-body fly apparel and apply fly repellent sprays generously.
• Feed and Hay Management: Soak hay to reduce dust particles and ensure that feed is free from mould or potential allergens.

What medications can help my horse with allergies?

While environmental management is crucial, medical interventions can swiftly alleviate symptoms:

• Antihistamines: Medications like cetirizine (Zyrtec) are effective at quickly reducing skin and respiratory symptoms. These can often be obtained over-the-counter and offer a relatively safe option for many horses.
• Corticosteroids: In cases of severe allergies, corticosteroids such as dexamethasone or prednisolone may be prescribed by a veterinarian. These drugs provide fast relief by suppressing the immune response but must be used judiciously due to the risk of side effects like laminitis.
• New Medications: Apoquel (oclacitinib) is a newer option that targets specific pathways in the immune system, potentially offering rapid relief without some of the risks associated with steroids.

How can I soothe my horse’s itchy skin caused by allergies?

Are there supplements that help horses with allergies? Lots of horse owners ask the question, ‘What can I give my horse for seasonal allergies?’ And it’s simple, feed Aloeride.

How can I prevent my horse from getting seasonal allergies?

While addressing immediate symptoms is crucial, implementing preventive measures ensures long-term relief:

• Vaccination and Desensitisation: In some cases, allergy shots (immunotherapy) might be an option in severe cases to gradually desensitise the horse to specific allergens.
• Supplements and Diet: Consider nutritional supplements that support the immune system and skin health, potentially reducing the severity of allergic reactions.

Combining these strategies effectively can lead to swift relief from seasonal allergies, enhancing your horse’s comfort and overall health.

Is there a link between seasonal allergies and colic in horses?

Horses, much like humans, can suffer from seasonal allergies, experiencing symptoms such as runny noses, watery eyes, hives, and even headshaking. While these allergic reactions are often manageable through dietary adjustments and environmental management, horse owners may wonder if seasonal allergies have any connection to more severe conditions, such as colic.

Colic refers to abdominal pain in horses and can range from mild discomfort to life-threatening conditions. It is a broad term that encompasses a variety of gastrointestinal issues, and its causes can include diet changes, dehydration, and stress. Given that colic affects the digestive system, it’s natural to question whether the systemic inflammation associated with allergies might contribute to the risk of colic.

There is no direct evidence to suggest that seasonal allergies cause colic in horses. However, there are indirect factors related to allergies that could potentially influence a horse’s susceptibility to colic:

1. Stress and Behavioural Changes: Horses suffering from allergies might exhibit stress due to discomfort from itching or respiratory issues. Stress is a known contributor to colic, as it can affect a horse’s digestive efficiency and lead to changes in gut motility.
2. Dietary Adjustments: In managing allergies, horse owners often make dietary changes, such as introducing fish oils or algae-based DHA supplements. Sudden dietary changes or inappropriate dietary management can disrupt the horse’s digestive system and increase the risk of colic. It’s essential to introduce any new supplements gradually and under veterinary guidance.
3. Digestive Health: As noted earlier, the digestive tract plays a significant role in a horse’s immune system. Ingredients like butyric acid and Saccharomyces cerevisiae yeasts are beneficial for maintaining gut integrity and regulating inflammation. If a horse with allergies has an inflamed or poorly functioning digestive system, it might be more susceptible to colic due to compromised gut health.
4. Environmental Factors: Seasonal changes that trigger allergies can also lead to changes in a horse’s routine, such as spending more time indoors to avoid allergens or changes in pasture availability. These shifts can contribute to an increased risk of colic, especially if they result in reduced exercise or altered feeding patterns.

Think Your Horse Might Have An Allergy? Always Consult With Your Vet

If you suspect your horse is suffering from an allergy, always begin by consulting with a veterinarian to accurately diagnose the allergies affecting your horse. A veterinarian can help distinguish between seasonal and other types of allergies and may recommend allergy testing to identify specific allergens. Seasonal allergies typically coincide with the periods of highest allergen exposure, generally from spring through summer. If the symptoms appear or worsen seasonally, this is a strong indicator that allergies might be at play.

While observing these symptoms, it’s important to differentiate between allergies and other potential health issues such as respiratory infections or dietary problems. If the symptoms persist and cannot be explained by other causes, allergies might be the reason and further investigation into equine allergies including skin testing may be necessary. This step is crucial in identifying a course of treatment and in developing a tailored management plan.
