How do I stop my dog overheating while hiking?

Checking a trail map or description for shade coverage, water crossings, and overall exposure before committing to a route helps you choose one genuinely suited to a hot day rather than discovering partway through that it runs entirely along an exposed, sun-baked ridge. A route with a stream or lake a dog can wade into periodically offers a natural, effective cooling opportunity that a dry trail cannot match.

Starting early enough to complete the most exposed or strenuous section of a hike before late morning heat builds matters considerably more for a hiking dog than for a dog on a standard neighborhood walk, given the extended duration and sustained exertion involved. Turning back or cutting a hike short if temperatures rise faster than the forecast suggested is a sensible response rather than pushing through to a planned endpoint.

Stopping for water and a few minutes of rest every 30 to 45 minutes, more frequently on very hot days or during a particularly strenuous uphill section, gives a dog's body regular chances to cool before heat builds to a dangerous level. Choosing rest points in shade specifically, rather than the first convenient flat spot regardless of sun exposure, makes these breaks considerably more effective.

Exposed uphill sections combine heat generation from exertion with direct sun exposure and are where overheating risk climbs fastest, so paying closer attention to panting, pace, and general demeanor during these stretches specifically, rather than only checking in at planned rest stops, catches a developing problem earlier.
