Welfare of Animals in Hot Weather Transport

Summer heat transport of livestock and companion animals is one of the most preventable sources of acute animal welfare emergencies.

Key Facts

Temperatures inside transport vehicles can exceed outside temperatures by 20C
Livestock transport during summer heat waves causes mass mortality events
Many EU countries restrict livestock transport during heat alerts
USDA regulations require 28-hour maximum transport without rest for livestock
Companion animal transport on airlines is restricted during summer heat alerts at many carriers

Welfare Considerations

Animals in transport during hot weather experience rapid hyperthermia that progresses from heat stress to organ failure and death. Livestock packed densely in trailers without ventilation can reach lethal temperatures within minutes of stopping. Companion animals in cargo holds of aircraft have died from heat exposure. The suffering during heat transport includes panting, agitation, weakness, and eventual collapse before death. These deaths are entirely preventable through temperature monitoring, restricted transport hours, and route planning avoiding peak heat.

What You Can Do

Never transport animals during peak heat hours in summer
Ensure all transport vehicles have adequate ventilation and shade
Advocate for heat-related livestock transport restrictions in your country
Support airlines and transport companies with strong heat protection policies for animals
