When you mentioned packing that reminded me. You should see if there's a group that does that kind of stuff in your area. The Alaskan Malamute Help League has various functions, including fun races and weight pulls, hikes etc. and something they call the pack 'n pull. Here's a link to some info about it: http://www.malamuterescue.com/09pnp.html
Beware of Mushers...They will suck you into their addiction!
If your dog thinks you're the best, don't seek a second opinion!
