On hot days, it is fundamentally import to offer your pet a source for shade and a water source for BOTH drinking and cooling. By providing plenty of shade and water for your pet at home, and by carrying water with you on hikes or daytrips, overexposure to heat can be easily avoided. Do not consider your dog house as an acceptable sole source of shade. Dog houses retain heat due to low (often no) ventilation and will heat up to dangerous and sometimes fatal temperatures. And of course, NEVER leave your pet alone in the car for ANY period of time, even with the windows cracked. The magnifying effect of glass can elevate interior the interior temperature of your care to fatal levels in mere minutes. This cannot be overemphasized. Never leave your dog unattended inside a vehicle for any period of time.
