00:005.5 million square miles of sand the size of China.
00:10The Sahara smothers 6% of the world's land.
00:15Yet this vast, unforgiving place is home to the world's smallest wild dog.
00:34The fennec fox.
00:36Barely the size of a walking boot, this tiny fox goes head to head with the desert every day.
00:52The Sahara's filled with millions upon millions of grains of sand.
00:58And every grain acts as a radiator.
01:02Sand absorbs heat, and the hotter it gets, the more heat it radiates.
01:12The temperature here spirals to over 100 degrees.
01:19In such sizzling conditions, the fennec's size matters.
01:24A small body can shed heat faster than a large one.
01:32And to lose heat even faster, the fennec's ears act like sophisticated air conditioning units.
01:39The network of veins cools the blood to lower the temperature.
01:44Despite such capable cooling, not even a fennec can endure the heat of the Saharan sun.
01:57There's no shade.
01:59But fennecs are masters of their environment.
02:03Moisture concentrates at the foot of the dunes.
02:06So the sand here is firm enough to dig a burrow.
02:11Home sweet home for a pair of fennecs.
02:19They have shelter from the worst of the heat.
02:23But they must eventually leave the safety of their den to find food.
02:27And this enormous desert is a dangerous place for a tiny wild dog.
02:39An unwary fennec is small enough to be caught by feral dogs and even eagle owls.
02:45But their camouflaged coats make them less conspicuous.
02:56In the fading light of dusk, she makes a run for it.
03:03Zig-zagging and jumping.
03:06She uses the dunes to mask her location.
03:11The grains of sand are constantly shifting.
03:15But the pads on her feet are furry for maximum traction.
03:20Few can keep tabs on her whereabouts.
