Check out the SP Kennel Dog Log, the blog of mushers Aliy Zirkle and Allen Moore. Extremely well-written and informative, it should be required reading for beginning dog mushers everywhere.
It's a behind-the-scenes look at a successful long-distance kennel, filled with great audio and video clips. They explain what it takes to prepare 2 teams for the Iditarod, the amount of training and dog care that goes into it, and the simple day-to-day operations of a professional kennel.
Aliy herself is well-spoken, generous with her knowledge, and good-humored. The video introductions of the dogs are a must-see!
Anyone interested in the mushing world would gain insight from this interesting and entertaining blog.
