Last summer, I built a couple of travois for my dogs and started training them to pull them with some of my gear on them.  They have done very well.  Cole can carry up to 35 lbs. on his travois, while Jessie usually carries 20 – 25 lbs.  Their inaugural outing was in September, when we attended an AMM camp near the Buffalo Peaks in the high mountains of Colorado.  In January, they really showed their stuff by pulling in to a camp near Grand Junction, CO.  The trail was narrow and snow covered along the side of a mountain.  We had some difficulty starting out, but soon got lined out and made the 1 mile trip without further trouble.  The trip back was easier yet, as more of it was down hill.  Miller documents a travois arrangement almost identical to the system I use for my dogs.  Notice the lop eared dogs.  Not the wolf eared dogs we usually think of as “Indian dogs”.
