"At the turn of the century sled-dog racing became
popular in Alaska. If there was one activity for which the
malamute was not ideally suited, racing was it. The
powerful, heavy-boned malamute was capable of pulling
great weights fro great lengths, but  it wasn't built for
acceleration or
speed. For this and for other expedient reason's
malamutes were breed with variety of lighter, faster
dogs"and purebreds were almost lost."

We should observe that purebred did not mean then with
it means today. Eskimos did not keep stud books, nor
did the Mahlemuts have signs posted by their dwellings
that read, "stud service to approved,registered bitches
only." Indeed, bitches in heat were sometimes staked
out for wolves to breed, wrote one historian.,"and the
toughness and adaptability of the malamute stock was
replenished." The notion that there were "purebred "
malamutes in Alaskan during the last century
or the early year of present on is a quaint, but imprecise,
fantasy."

History
"This is he sled dog of stamina and strength
rather than speed. It gets is name from the
malamute tribe, an Inuit
people of northwestern Alaska, these
nomadic Eskimos used the dogs to haul their
possessions between camps.

The breed type was stabilized in the 1920's
and accepted for showing in the American
Kennel Club in 1935. After that
it gained immense recognition because of it's
use as a war dog."

"The most celebrated of all Eskimo dogs was
the malamute, a type bred by Mahlemut tribe,
which lived near Kotzebue Sound on the
northwest coast of Alaska.


(Kotzebue, ironically, was a German opera
librettist and
playwright noted for his superficial and often
sensational melodramas and comedies.)


"The Mahlemuts' dogs, according to one
observer were less"wild and more tractable
than other arctic strains, and were capable of a
variety of tasks from pulling sledges to hunting
seals to chasing down polar bears.
Such was the prowess of the
malamute that Eskimos who lived
inland traveled down the Kobuk and
Noatak river to Kotzebue Sound to
trade furs for dogs and supplies.
Thus did malamutes find their way to
other regions of Alaskan and even to
adjacement parts of the Yukon, where
they gold diggers and some of the
dogs that had accompanied them to
the Yukon  made the malamute'
acquaintance 100 yrs ago. (
Additional testimony to the malamutes
hegemaon was the use of the word
malemutes to indicate any
freight-pulling dogs."

Malamutes were further distinguished their
strength, reliability, wide-ranging of colors and
unique marking. Their ancestors are thought to
have migrated from Siberia to Alaska across
the Bering land bridge in the company of
nomadic tribes.

More than twice the size of Texas, the Bering
land bridge connected Siberia and Alaskan
until rising seas dumped 800 feet of water over
it 11,000 years ago, when summer
temperature in that part of the world were sight
to 11 degrees warmer than they are now.
