Actually, I looked in Amazon.com (have a coupon to use) to see more
about the book, since it looked more interesting than the standard
Iditarod book
I was trying to see how much of the original serum run
story they told. Any comments on the book in general?

The modern racing dogs are like pro marathoners - small and fast. They
are a hybrid, but I can't remember what breeds might be involved - or
*if* there is any standard. Other dogs have been bred for heavy pulls,
like a tractor pull contest. Today's racing dogs are pulling sleds and
loads that are much lighter than the older ones.

"Their food includes lots of protein, fat, and other high energy stuff.
Some mushers make their own concoctions from ingredients like fish,
hamburger, beef, horse meat, lamb, beaver, moose, caribou, and sometimes
even seal meat."

Just some examples of research. Keep in mind that the top long-distance
dogs are professional athletes, although it's usually the musher that
gets the sponsors, not the dogs themselves.

I think Iams has probably done a fair amount of research also.
Sometimes, if we're lucky, they monitor the human performance as well as
the dog's so we learn more about human physiology in cold weather sports.
Google would probably pull up more on dog nutrition. I just posted a
couple relevant links.
