During periods of heavy rainfall, many horse owners may notice the emergence of rain rot in their horses. This skin condition can be frustrating, but with proper care, it is often manageable.

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.

Respiratory disease is one of the most important health concerns facing the horse industry, and accounts for one of the biggest reasons why horses miss training days (Rossdale et al., 1985). Equine asthma, also known as “heaves,” is one of the more troublesome small airway diseases which causes an elevated respiratory rate, chronic coughing and runny nose, and affected horses often find it difficult to exhale.
