The effectiveness of your horse or pony's respiratory system is affected by a number of factors, including viral or bacterial infections, lowered immunity, poor air quality, or seasonal airborne allergens such as pollen. Any of these can lead to respiratory irritation, behavioural problems, a reduction in respiratory health, lung function or ability to perform. We have a range of pure herbal supplements and fast-acting liquid solutions to maintain healthy lungs, airways, sinuses and resistance to environmental allergens.
