What is COPD in horses and what are the effects of the disease?
In short, COPD describes a chronic lung disease characterized by mucus production and/or swelling or spasming of the airways – which can lead to shortness of breath.
When it comes to respiratory diseases, many first think of coughing. However, with COPD, coughing is not always obvious because the amount of mucus can be so small that the horse swallows it instead of it visibly running out of the nose. When coughing does occur, it is often either persistent or situation-dependent, such as when eating dusty or moldy hay. #FYI: This is not a hay dust allergy but a situation-related worsening of the respiratory disease due to the additional strain.
Another typical feature is the altered breathing of the horse. In severe cases, both inhaling and exhaling can be very difficult. This often leads to enlargement of the oblique abdominal muscles (“dorsal groove”), as the horse needs more effort to press the air out of the lungs. This process, also called “abdominal press,” is a clear sign of chronic respiratory problems.
Since the airways are already heavily burdened by COPD, the horse’s performance decreases. However, exercise remains important and must be individually adapted to the horse’s capacity. Light, dust-free exercise sessions in fresh air can help here.
The #SYMPTOMS at a glance
- Coughing that lasts for a longer period (at least 6 weeks)
- Shortness of breath and noticeable abdominal breathing
- Decreased performance under strain
- Nasal discharge, often accompanied by clear or slightly mucous secretions
What causes #COPD?
#Infections
Acute respiratory infections must be completely healed. Give your horse enough time to recover before putting it under strain again. Too early or too intense exertion can cause the infection not to fully subside and may develop into a chronic disease like COPD.
#Housing conditions
Persistent irritation of the airways can be promoted by various factors and lead to COPD in the long term. Particularly problematic are ammonia exposure in the stable and fine dust from hay and straw. This fine dust contains mold spores, mycotoxins, and other particles that can irritate the mucous membranes and burden the airways.
#Feeding
The quality of the feed also plays a crucial role. High-quality hay and straw contain low amounts of fine dust, but the exposure is many times higher with poor-quality or moldy feed. To protect your horse’s airways, always ensure impeccable feed quality.
#Allergies
If the lungs are already irritated, they become more sensitive to additional burdens like dust or fumes. Allergies often develop against mold spores or other fine dust particles. A pre-damaged lung can also overreact to other stimuli such as pollen or extreme temperatures. This often leads to hypersensitivity, which further complicates breathing.
How is COPD diagnosed?
Diagnosing COPD requires a comprehensive examination by a veterinarian. A combination of various diagnostic methods is used to get the most accurate picture of the condition of the airways:
- Clinical examination: The vet listens to the horse’s lungs and observes its breathing, paying attention to unusual breath sounds or increased abdominal breathing.
- Endoscopy: Using a small camera, the vet directly examines the airways. This can reveal mucus accumulations, inflammations, or bronchial constrictions.
- Blood and secretion analyses: Blood samples can detect inflammation markers. Secretion samples from the airways provide important clues, such as allergic reactions or bacterial infections.
Early diagnosis is crucial to initiate appropriate measures in time. This can slow the disease progression and help your horse maintain a good quality of life despite COPD.
Treatment of COPD
A complete cure is usually not possible, but targeted measures can alleviate the symptoms:
Optimizing housing
It makes sense to carefully consider your horse’s stable and current housing conditions. If your horse is kept in a box stall, switching to an active or open stable can bring significant improvement. Also, make sure to use dust-free bedding or wood pellets. Ensure good ventilation in the stable and reduce dust sources, for example by using steamed or soaked hay.
Inhalation
Inhalation in horses is a proven method to support the airways and relieve symptoms such as coughing, shortness of breath, or mucus-filled bronchi. Especially with respiratory diseases, this therapy offers gentle and effective support because the active ingredients reach the lungs directly and can unfold their effect there. Moistening the mucous membranes loosens stubborn mucus and makes breathing easier.
Mobile inhalation devices offer a particularly practical solution. They allow you to move your horse at a walk during treatment, which deepens breathing and promotes absorption of the active ingredients. Using a special saline solution additionally provides optimal care for the airways. A 20- to 30-minute walk during inhalation can further enhance well-being. To perfectly tailor the therapy to your horse’s needs, always consult your veterinarian beforehand.

Steaming hay and straw
More and more horse owners moisten their horses’ hay, especially in cases of allergies. Although this method can be time-consuming, it offers an effective way to relieve the airways and ease symptoms.
A modern alternative is hay steaming devices. These thoroughly clean the roughage from dust, mold, and bacteria, significantly improving feed quality. Since horses constantly inhale fine dust and mold particles while eating, using a steaming device noticeably relieves the airways and contributes to your horse’s health.
Adjusting training
If the mentioned treatments do not bring the desired success, training should be individually adjusted. Keep your horse moving, but only at a relaxed and moderate pace. It is important first to identify the exact causes of the breathing difficulties and treat them specifically.
Always keep an eye on your horse’s symptoms and respond quickly to changes. Especially during demanding times like coat changes or extreme weather conditions in winter and summer, symptoms can worsen. Even if your horse usually copes well with the disease, attention and flexible adjustment of measures are essential.
Prognosis with COPD
The long-term prognosis for a horse with COPD largely depends on how early the disease is detected and how consistently the recommended measures are implemented. Although COPD is not curable, quality of life can be significantly improved through adapted housing, feeding, and therapy. Many horses live active and content lives despite the chronic disease if their airways are consistently relieved and irritants minimized.
It is important that you, as a horse owner, continuously monitor the symptoms and react early to any changes. With good care and the right measures, symptoms can usually be well controlled. Regular consultation with the veterinarian and adjusting therapy to your horse’s individual needs are crucial to ensure long-term stability and well-being.
Integrating gentle exercise sessions and avoiding stress factors also help protect the airways and promote overall well-being. With proper care and housing, many horses with COPD can enjoy a fulfilling life for years to come.
