Every summer, as temperatures rise, so does the danger of pets dying because carless owners left them in a hot car. While humans cool themselves by relying on an extensive system of sweat glands and evaporation, dogs and other animals have a harder time staying cool, leaving them extremely vulnerable to heatstroke.
Parked cars quickly trap the sun's heat. Even on a day when it's 70 degrees outside, the temperature inside a car with the windows rolled up can hit 90 degrees in just 10 minutes. On a hot day, the temperature inside a closed car can shoot as high as 130 degrees in the same amount of time. -Source animal legal defense fund, www.aldf.org.
Now, for those of us in the Imperial Valley, leaving your dogs in the car with the windows cracked isn't an option. Each minute that passes means increased danger for your dog, who can become overheated ad suffer from heat strock in a matter of minutes. Untreated, he/she can go into cardiac arrest and die.
Sadly, veterinarians throughout the country expect to be trating far too many dogs for heat-related conditions during the summer and early fall. Signs of heat stroke include excessive panting, agitation, vomiting, weakness and collapse.
