A hot humid day. One rider. One horse. Both are exercising at a moderate level. Who is more likely to overheat? It might surprise you to learn that your horse gets hotter much faster than you and is more susceptible to the negative effects of heat stress. Prof. Michael Lindinger, an animal and exercise physiologist at the University of Guelph, explains: “It only takes 17 minutes of moderate intensity exercise in hot, humid weather to raise a horse’s temperature to dangerous levels. That’s three to ten times faster than in humans. Horses feel the heat much worse than we do.”

Parasite prevention remains a vital part of maintaining horse health—but gone are the days when you could rely on a routine deworming every eight weeks with the same product.

Better for the Horse. Better for the Rider. “We recommend ThinLine for horses that are back sore, horses that have saddle issues, and to help reduce the impacts that riding has on horses,” says FEI certified veterinarian Dr. Fernando Cardenas in North Carolina, USA who also breeds warmblood sport horses.

How flies spread parasites and disease - Flies are the bane of many horses’ existence from spring through autumn. In Canada, horse-biting flies include gnats (no-see-ums), black flies, stable flies, deer flies, horse flies, and mosquitoes, all of which create painful sores. Non-biting flies include house flies, eye gnats, face flies, bot flies, and warble flies, and can be just as irritating. It’s not just buzzing and biting that’s worrisome; flies may transmit parasites and diseases, can cause a horse’s immune system to overreact, and some use horses as hosts, all of which impact horse health. Preventing horses from being bitten is key. Before diving into solutions, here’s a summary of the damage that flies can inflict on Canada’s horses.

The Inside Story - For as long as horses have been grazing the hillsides and meadows, the pest of parasite infestation has plagued them. Perennial as the grass, intestinal parasites find every possible opportunity to enter their horse host, and live out their life cycle.
