- Helps reduce secondary infections

How does congestion occur?
Airways in horses become congested in response to airborne particles such as dust, pollen and moulds. It is crucial to free the airway of inhaled particulates and also to ward of the potential for secondary bacterial infections. Blocked or congested airways causing thick nasal discharge may cause distress and also lead to chronic or acute conditions such as heaves to equine pneumonia.
Mucous can also be triggered in response to an allergen. This is the bodies attempt to capture the particles where the body can then remove. However, when congestion is thick it may need the help of a product like Expel to assist in removal.
It is best practise to reduce the mucus and take practical steps to reduce allergens.
Expel is an airways supplement for horses to help free mucus from the airway. It may also be used as a short-term supplement during coughs and colds if congestion is present.

FAQ
All your questions, answered.


Not sure what rug your horse needs right now? Our free Horse Rug Forecaster checks your local weather and tells you what rug weight your horse needs today, tonight and over the next 3 days. It works anywhere in New Zealand and adjusts for clipped horses and horses that feel the cold.
The thermoneutral zone is the temperature range where the body can maintain its core temperature with little to no extra energy expenditure. Humans need it much warmer, at around 25–30 °C, but for horses it’s much broader at 5–25 °C.
This difference means we should avoid rugging horses based on how cold we feel. Over-rugging can lead to serious health issues, including metabolic problems and thermoregulatory dysfunction.
Tips for Choosing a Winter Rug Weight
-
Clipped horses may need a heavier gram fill to stay comfortable.
-
Remember: horses warm themselves more easily than they cool down under a rug. If unsure, choose a lighter rug.
-
Check your horse regularly to make sure they are neither too hot nor too cold.
-
Consider your horse’s age and natural ability to stay warm.
-
As a general guide, a healthy unclipped horse with shelter usually doesn't need a winter rug until it feels colder than about 5 °C, but always adjust for your horse’s individual needs.
-
Always ensure rugs are waterproof. A wet rug is worse than no rug at all.
This is an indicative guide only. Always take into account factors such as wind chill, your horse’s age, weight, and condition. For advice based on your local forecast, try the Horse Rug Forecaster.
