During the summer there are often waves of horses presenting with respiratory disease. Ontario Veterinary College researcher, Janet Beeler-Marfisi, never really ascribed that to being part of air pollution until her recent research revealed that horses, with their far greater lung capacity and athleticism, can also suffer when air pollution levels rise.

Eastern equine encephalitis virus (EEE), also known as sleeping sickness, and Western Equine Encephalitis (WEE) are viral diseases that cause inflammation of the brain and spinal cord. Wild birds are a natural reservoir for EEE and WEE viruses, and mosquitoes that feed on these birds can transmit the virus to mammals, including horses and humans.

It’s safe to say that horse owners across Canada are passionate about their horses and their industry. Whether they are pleasure riders, competitors, or those who breed or train horses for a living, Canadian horse owners are invested in the equine industry both emotionally and financially. We read, we research, and we invest in them in the hopes of having the satisfaction of seeing a healthy horse in our barn or a successful one in the arena. Sometimes we are faced with making decisions about the welfare of our horses, and although social media is filled with opinions on what is the “best” thing to do for them, it isn’t always obvious as to what is the “right” thing to do for them.

Does your horse have trouble responding to the bit? Does he hold his head awkwardly at times, or seem to have problems chewing? Does he show unexplained behaviour under saddle or have problems with certain gaits or leads? Or does he toss his head a lot, especially when pressure is applied with his bit or perhaps a hackamore?
