When your horse is coughing, sneezing, or otherwise suffering from breathing issues, it becomes an immediate cause for concern, as it may affect not only athletic performance but also overall quality of life. Respiratory problems in horses are common, but the good news is that many are highly treatable and manageable with prompt veterinary care and proper management.
What Infections Cause Respiratory Problems In Horses?
One of the most common reasons horses develop respiratory problems is bacterial or viral infection contracted from another horse. Contagious respiratory diseases can spread quickly in barns, at competitions, or during travel.
Common infectious causes include:
- Strangles
- Equine herpesvirus
- Equine influenza and other viral respiratory infections
It is possible for horses to shed bacteria or viruses for weeks after recovering from an illness. Some horses can even shed pathogens while appearing completely healthy. Because of this, assume that any new horse introduced to your stable, or any horse encountered at events, may pose a risk of transmitting infection.
To reduce the risk of infection:
- Never share tack, grooming tools, or feed buckets between horses
- Avoid communal water sources
- Wash your hands after handling other horses
- Change or disinfect clothing and boots that may be contaminated
If your horse develops respiratory symptoms along with a fever, they are likely suffering from an infection. Contact your veterinarian for an examination to determine severity and whether your horse needs rest, isolation, or prescription treatment such as medications found in the Horse category.

Respiratory Problems In Horses Caused By Their Environment
Not all respiratory problems in horses are contagious. Environmental factors frequently play a major role in chronic airway inflammation.
If your horse has lingering respiratory issues without a fever, they may be experiencing airway inflammation worsened by dust, mold spores, or allergens in their environment.
Recurrent Airway Obstruction, also known as heaves, is common in older horses and is typically triggered by an allergy to organic dust found in hay or bedding. Inflammatory Airway Disease, or IAD, is more common in younger athletic horses and affects an estimated 22 to 50 percent of performance horses. Symptoms often appear during exercise and may include coughing or mild nasal discharge, while the horse otherwise appears healthy.
Management strategies may include:
- Improving ventilation in the barn
- Soaking or steaming hay to reduce dust
- Switching to low-dust bedding
- Increasing turnout time
Your veterinarian may prescribe corticosteroids or bronchodilators to control inflammation and improve breathing. You can also find supportive products for airway health in the Horse Care category.
Other Causes Of Respiratory Problems In Horses
If your horse has respiratory symptoms, the underlying cause may not be obvious, as many conditions share similar signs.
Coughing, flared nostrils, and labored breathing may also be associated with:
- Cardiovascular issues
- Pain or stress
- Trauma
- Systemic illness
Because symptoms often overlap, it is imperative to consult your veterinarian for an accurate diagnosis and appropriate treatment plan. Early intervention can help protect your horse’s performance, comfort, and long-term respiratory health.
