HORSES ARE MAMMALS KNOWN AS
UNGULATES.

THAT MEANS THEY HAVE HOOVES.

HORSES ARE RELATED TO OTHER
UNGULATES LIKE COWS OR ZEBRAS.

THE PEOPLES OF NOMADIC MONGOLIA
WERE THE FIRST TO DOMESTICATE

HORSES AND BY 1,000 BCE CHINESE
OFFICERS USED HORSE-DRAWN

CHARIOTS IN BATTLE.

EMILY SLOOP: HORSES ARE PREY
ANIMALS.

THEY ARE BUILT FOR SPEED AND
STRENGTH.

CARTAN-HANSEN: HORSES HAVE TOUGH
HOOVES TO PROTECT THEIR FEET

FROM POUNDING.

THEY CAN RUN OVER ROUGH GROUND
WITHOUT INJURY BECAUSE THEIR

LEGS MOVE FORWARD TO BACK, NOT
SIDE TO SIDE, AND THEIR LEGS ARE

WELL SPACED TO COVER LOTS OF
GROUND WITH EACH STRIDE.

HORSES HAVE THE LARGEST EYEBALLS
OF ANY LAND MAMMAL.

A HORSE'S EYES ARE SET HIGH UP
AND TO THE SIDE OF ITS HEAD SO

IT CAN SEE ALL AROUND.

ITS EARS CAN SWIVEL 180 DEGREES
LIKE RADAR DISHES.

A HORSE HAS EXTRA LARGE NOSTRILS
BECAUSE IT CAN'T BREATHE THROUGH

ITS MOUTH.

HORSES ARE HERBIVORES.

THEIR LARGE TEETH HAVE A LONG
GRIPPING EDGE, PERFECT FOR

CUTTING AND PULLING UP GRASS,
AND BECAUSE THOSE TEETH WEAR

DOWN AFTER YEARS OF CHEWING,
HORSES' TEETH GROW THROUGHOUT

THEIR LIFETIMES, AND HORSES HAVE
A LONG NECK TO ALLOW THEM TO

GRAZE WITHOUT HAVING TO BEND
THEIR LEGS.

KATIE ANDERSON: HORSES ONLY
SLEEP FOR ABOUT THREE HOURS A

DAY AND LIE DOWN ONLY FOR A
SHORT REST.

CARTAN-HANSEN: HORSES HAVE FOUR
SPEEDS CALLED GAITS.

THEY WALK.

THAT'S THEIR SLOWEST SPEED.

NEXT IS A TROT, A LITTLE FASTER
THAN WALKING.

NEXT A CANTER, FASTER THAN A
TROT.

AND THEN A GALLOP, A HORSE'S
FASTEST GAIT.

WHEN HORSES ARE BORN THEY'RE
CALLED A FOAL.

A FOAL CAN WALK SOON AFTER
THEY'RE BORN.

A YOUNG MALE IS CALLED A COLT.

A YOUNG FEMALE IS CALLED A
FILLY.

A HORSE IS CONSIDERED TO BE AN
ADULT AT FOUR.

HORSES ARE MEASURED IN HANDS, A
UNIT FIRST USED IN ANCIENT

EGYPT.

SLOOP: A HAND IS SET AT FOUR
INCHES, AND A HORSE'S HEIGHT IS

MEASURED FROM THE GROUND TO ITS
WITHERS, THE BUMP BETWEEN ITS

NECK AND BACK.

CARTAN-HANSEN: HORSES COME IN
ALL SHAPES AND SIZES AND

DIFFERENT COLORS.

THERE ARE MORE THAN 200
DIFFERENT BREEDS OF HORSES.

THE SMALLEST ARE SHETLAND PONIES
THAT CAN BE ABOUT SEVEN HANDS OR

ABOUT 28 INCHES TALL.

THE TALL BREEDS LIKE THE SHIRE
CAN BE UP TO 19 HANDS TALL AND

WEIGH MORE THAN 2,000 POUNDS.

HORSES HAVE BEEN BRED TO DO LOTS
OF DIFFERENT THINGS.

LARGE HORSES OR DRAFT HORSES
PULL WAGONS.

RANCH HORSES HELP WORK WITH
CATTLE.

THOROUGHBRED HORSES CAN GALLOP
FASTER THAN ABOUT 37 MILES PER

HOUR.

WILD OR FERAL HORSES ARE
DECENDENTS OF ANIMALS TURNED

LOOSE OR ESCAPED FROM EARLY
SPANISH EXPLORERS OR LATER FROM

SETTLERS OR PEOPLE WHO ABANDONED
THEIR ANIMALS.

IT ONLY TAKES ONE GENERATION TO
TURN A DOMESTICATED HORSE INTO A

WILD HORSE.

THERE ARE ALMOST 50,000 WILD
HORSES, WAY TOO MANY FOR THE

HERDS TO SURVIVE, SO THE BUREAU
OF LAND MANAGEMENT AND OTHER

AGENCIES OCCASIONALLY ROUND UP
WILD HORSES FOR ADOPTION.

ANDERSON: A HORSE REQUIRES A LOT
OF CARE.

YOU NEED TO BRUSH HIS COAT, FEED
HIM, WATER HIM, EXERCISE HIM AND

GIVE HIM A GOOD CLEAN PLACE TO
LIVE.

YOU NEED TO DO IT FOR A LONG
TIME, TOO, BECAUSE A HORSE CAN

LIVE WELL INTO HIS THIRTIES.

CARTAN-HANSEN: HUMANS HAVE A
STRONG RELATIONSHIP WITH HORSES.

THEY'VE WORKED FOR US.

THEY'VE BEEN OUR COMPANIONS.

TO PARAPHRASE WINSTON CHURCHILL,
THE OUTSIDE OF A HORSE IS GOOD

FOR THE INSIDE OF A PERSON.
