Heatstroke

Heatstroke is a very serious medical emergency.  The combination of high temperatures, high humidity, and poor ventilation can be fatal to dogs and cats.  Panting and radiation of heat from the skin surface are their main means of controlling body temperature. If the air temperature and humidity are high and air circulation is reduced, these protective measures are rendered ineffective.  Body temperature can rise radically, resulting in collapse and severe shock.  Dogs with short, flattened noses, such as Pugs, Bulldogs, Pekingese, and Boxers are very susceptible to heat stroke, due to their restricted breathing. Common symptoms of Heat stroke include:

Panting

Disorientation

Refusal to obey commands

Listlessness

Dark red or purple gums and tongue

Rapid heartbeat

Vomiting

Collapse

Do not leave your pet in the car.  The temperature inside a car can rise as much as 40 degrees in under an hour.  On an 85-degree day, the temperature in a car can reach over 100 degrees even with the car windows cracked.  Even if you only have to run a few errand is safer to leave your pet at home.
