The bite of Culicodes midges builds rashes on the necks, belly parts, docks which is the allergic reaction none other than a sweet itch. Horses rub, scratch and bite on these areas when they are facing this disease. Bites of mosquitos, horseflies, deerflies, stable and black flies, mites, in some cases fleas can also trigger allergies.

Histamines can be present in the plants which you give the horses as feed. Horses can also produce histamines which are very friendly content to create allergies.

As an example, you are taking your horse to exercise but the horse is doing lots of snorting. The reason behind this is he is suffering from the nasal membranes’ irritation. Throat clearing cough is also common when you trot or canter the horse for the first time.
If you wish to keep the problems out, apply Vaseline nearby the noses opening to reduce the exposure. Further breathing problems follow these may turn into asthma.
