PETA makes the following suggestions for safeguarding animals:
• Keep dogs inside: Unlike humans, dogs can only sweat through their footpads and cool themselves by panting. Soaring temperatures can cause heat stress, injury, or death.
• Water and shade: If animals must be left outside, then they should be supplied with ample water and shade, and the shifting sun needs to be taken into account. Even brief periods of direct exposure to the sun can have life-threatening consequences.
• Walk, don't run: In very hot, humid weather, never exercise dogs by cycling while they try to keep up or by running them while you jog. Dogs will collapse before giving up, at which point, it may be too late to save them.
• Avoid parked cars: Never leave an animal in a parked car in warm weather, even for short periods with the windows slightly open. Dogs trapped inside parked cars can succumb to heatstroke within minutes—even if a car isn't parked in direct sunlight.
• Never transport animals in the bed of a pickup truck: This practice is dangerous—and illegal in many cities and states—because animals can catapult out of a truck bed on a sudden stop or choke if they jump out while they're tied up.
• Stay alert and save a life: Keep an eye on all outdoor animals. Make sure that they have adequate water and shelter. If you see an animal in distress, provide him or her with water for immediate relief and then contact humane authorities right away.
