Mud fever—also called greasy heel, scratches, or pastern dermatitis—is a skin disorder that commonly affects the lower legs of horses, especially around the heels and pasterns. It occurs most often in the wet seasons of fall, winter, and early spring, when horses spend long hours in muddy conditions that allow bacteria and fungi to multiply.

The shorter, cooler days of autumn herald the approach of the cold winter months. Starting with the spring season, we all race around to participate in shows, rodeos, or backcountry camping trips. When those exciting events wind down, we can focus on all the tasks we’ve put off — those “before winter rolls around” jobs.

Horses are commonly housed in individual boxes. While this may be convenient and prevent injuries from other horses, it may also be detrimental to the horse’s welfare, especially if access to pasture is limited. A paper by Alice Ruet and colleagues investigated the effect of various management practices on the display of behavioural indicators of compromised welfare in housed horses.

Climate change is increasingly affecting horses, horse properties, and their owners across Canada. In recent surveys, nearly 90 percent of Canadians reported noticing the impacts of climate change in their communities. Horses are facing rising health risks, including respiratory diseases from wildfire smoke and dust, skin conditions and hoof damage caused by unpredictable weather, and new parasites and diseases. Horse owners are also dealing with higher hay costs, unexpected veterinary expenses, and challenges related to weather disruptions, such as riding limitations. Meanwhile, owners of horse properties are working to repair damage from severe storms, flooding, droughts, and high winds.
