Never leave an animal alone in a vehicle, since even with the windows open, a parked vehicle can quickly become a furnace. Parking in the shade offers little protection. In the shade, with the windows open, the temperature reaches 102 degrees in 10 minutes, and 120 degrees in 30 minutes on an 85-degree day. Always exercise your pet in the cool of the early morning or late evening. Hot pavement can mean hot or burned paws.
Pets are much closer to the hot asphalt or concrete, and their bodies can heat up quickly.
Do not leave them standing on the pavement. The hard plastic baby pools filled with cool water can be fun and cooling for most dogs. These chemicals can sicken or kill an animal. Animals are attracted to the sweet taste, and just a small amount can cause death. Consider using animal-friendly coolants that use Propylene glycol.
