My favorite quote from the article is this, "each approximately 55-pound sled dog can burn up to 12,000 kilocalories per day, which is the equivalent of 24 McDonald's Big Macs. A human would have to consume and efficiently process the equivalent of 72 Big Macs to fuel a day's Iditarod run."

Pretty amazing dogs! Here is a preview for Discovery's newest show about the Iditarod.
Toughest Race on Earth: Iditarod series premier will start next week, 10/14.
For those of us that don't have furry friends that appreciate those cold nights, here is a little plug for some winter beds!
