What happens if a Husky gets too hot?

The Husky is a Siberian sled dog from cold climates with low heat tolerance. In summer heat it pants often, drools, drinks more and lies in shade, unwilling to move. If heat rises or it is exercised in peak heat, it can get heatstroke; mild cases bring lethargy, low appetite, fast breathing and slow gait, while severe cases cause breathing difficulty, full-body seizures, sudden collapse and foaming at the mouth.
