Heatstroke is a deadly disease that can kill your beloved companion, even with emergency treatment. The best way to avoid this terrible situation is prevention, and it's all up to you. Everyone knows that the inside of a car on a hot summer's day can be lethal. But Fido needs you to know more than that to keep him safe in the deadly sun. Days above 90 degrees, especially with high humidity, are inherently dangerous for your pet.
Humidity interferes with animals' ability to rid themselves of excess body heat.
When we overheat we sweat, and when the sweat dries it takes excess heat with it. Our four-legged friends only perspire around their paws, which is not enough to cool the body. To rid themselves of excess heat, animals pant. Air moves through the nasal passages, which picks up excess heat from the body. As it is expelled through the mouth, the extra heat leaves along with it.
