Respiratory problems in horses are more common than you think, especially during stable season or in dusty conditions. The symptoms can be subtle at first, but they always deserve attention.

 

Do you recognize these signs?

• Coughing: especially when starting to ride
• Nasal discharge: clear or slightly mucous-like
• Rapid or labored breathing: even at rest

If you notice one or more of these symptoms, always consult your vet first. Only a vet can determine whether it’s something serious, like COPD or infection.

1. Soaking hay = less dust, easier breathing

Dust is one of the biggest triggers for respiratory issues in horses. Hay in particular can contain fine dust particles and mold spores, even if it looks perfectly fine to the eye.

A common method to reduce this is soaking the hay. By submerging the hay in clean water for 20 to 30 minutes, the dust particles bind to the moisture. Be sure not to soak it for more than 1 hour to prevent bacterial growth.

An alternative or addition to this is the Herbimals Hay Spray – a ready-to-use, 100% natural spray based on essential oils such as eucalyptus, pine, thyme, and peppermint. This spray binds dust particles, supports the respiratory system, and in many cases makes soaking unnecessary.

 

2. Herbs that help ease the airways

Some plants and herbs have been known for centuries for their soothing effect on respiratory irritation. In nature, horses instinctively select herbs that help keep them healthy and support easier breathing — from aromatic plants to those rich in mucilage.
Note: herbs are not a medicine, but they can have a soothing effect.

Here are some examples of herbs that can contribute to respiratory comfort:

• Thyme (Thymus vulgaris): An aromatic herb traditionally used to help loosen mucus and cleanse the airways.

• Ribwort plantain (Plantago lanceolata) and Broadleaf plantain (Plantago major): Contain natural mucilage that can soothe irritated mucous membranes in the throat and airways.

• Chamomile (Matricaria chamomilla): Known for its mild, calming effect and often used for light inflammatory reactions.

• Marshmallow root (Althaea officinalis): Rich in mucilage and traditionally used to coat the throat and airways during dry irritation.

You can feed these herbs fresh. If they’re not available fresh, you can use dried herbs. Offer them preferably via self-selection, allowing your horse to choose what it needs.

Feed the herbs separately and in the coarsest form possible. This preserves the natural scent and structure, which improves recognition for your horse and supports self-selection. Coarser herbs also retain their active compounds better than ground versions. Only in specific cases, such as with horses that ball up hay or have difficulty chewing, should you consider using finer herbs.

You can also make a tea from the herbs and, based on self-selection, offer it to your horse once cooled.

3. Nebulization & fresh air

Clean, well-ventilated air is essential for any recovery. A nebulizer with saline (0.9% NaCl) helps loosen mucus and moisturize the airways.

Ensure proper airflow in the stable without drafts. Avoid moldy bedding and ventilate daily.

4. Tailored nutrition: fiber-rich, dust-free & gentle on airways

What your horse eats affects its breathing. Choose low-dust, high-fiber feeds that support calm digestion.

• BalanceFit Timothy is a complete balancer made from timothy grass – naturally low in sugars and dust, suitable for horses sensitive to alfalfa or coarse roughage.

• NaturalFit HayCobs are fiber-rich hay pellets that can be soaked into a dust-free mash – gentle on airways and easy to chew.

Both are grain-free, low in sugar, and high in fiber. When soaked, they reduce airborne dust and support hydration.
