May 23 is National Heat Awareness Day, sponsored by the National Weather Service to remind us of just how dangerous heat can be, not only to humans, but to pets.
As shown on this NWS web page about the dangers of heat to children and pets, even when the temperatures are relatively mild, the interior or a car or truck can heat up very quickly. To reveal more details, click the links on the page.
Also addressing this same issue is a brief video from the American Veterinary Medical Association.
We agree with the advice from the AVMA. If you love your pets, leave them at home!
