Features of thermoregulation in labradors make them very susceptible to heat. Dogs in natural conditions in the heat have the opportunity to go into the shade or hide in a hole. Vessels located close to the surface of the skin expand, the volume of blood flow increases, and heat transfer to the environment increases five to six times.
