Dogs exercising in hot weather face serious heatstroke risk that owners frequently underestimate, with breed differences creating substantial variation in heat tolerance.
Hot weather exercise management is a welfare issue where owner decisions directly determine whether dogs suffer heatstroke. The risk is frequently underestimated because dogs typically continue trying to exercise with their owner even when physiologically dangerously overheated - their social motivation overrides the self-preservation signals that would cause a healthy animal to stop. Owners who do not recognize this or who misread panting as normal exercise response can inadvertently push dogs to heatstroke. The welfare solution is simple but requires discipline: exercise at cool times of day, monitor for early signs, and stop immediately if panting becomes excessive. For brachycephalic breeds, summer exercise must be drastically curtailed and cool indoor environments prioritized.
