Dog Heat Stress and Summer Welfare

Summer heat poses serious welfare risks to dogs beyond the well-known hot car danger. Understanding all the ways dogs experience heat stress enables comprehensive prevention.

Key Facts

Dogs with flat faces (brachycephalic breeds), dark coats, obesity, and certain medical conditions are at disproportionate heat risk
Exercise on warm days increases internal heat production faster than dogs can dissipate it through panting
Humid conditions significantly impair evaporative cooling through panting, dramatically reducing heat tolerance
Road surfaces can reach 70°C+ on hot days — paw burns and radiant heat at dog nose height compound heat stress
Cooling down a heat-stressed dog with cool (not ice cold) water, fans, and shade is effective first aid before veterinary transport

Welfare Considerations

Summer heat stress in dogs is a broader welfare problem than its most famous manifestation — hot car deaths. Dogs who are exercised vigorously in hot, humid weather, walked on hot pavements at midday, or who have conditions that impair heat dissipation face welfare risks in many everyday contexts. The welfare-positive approach is systematic: time walks to early morning or evening in summer, test pavement temperature before walking, provide shade and cool water at all times, and recognize brachycephalic breeds as chronically heat-vulnerable animals requiring extra management during warm weather. Prevention is far preferable to treating heat stroke.

What You Can Do

Walk dogs before 8am or after 7pm during hot summer weather
Carry water and offer it frequently during summer exercise
Test pavement temperature with the back of your hand for 7 seconds before walking
Provide a paddling pool or cool mat for garden-dwelling dogs during hot weather
Keep brachycephalic breeds in air-conditioned environments during heatwaves
