I just sewed two widths of Tyvek together to make a decent sized ground tarp to hang out on around the fire. Sewed just like any other fabric. Mule

You've probably thought of this but you might want to take some boots for your dog. I was hiking down around the San Antonio area (lots of rocks) and this family's dog had torn up his pads really bad. I know the AT isn't as rocky in most places and your dog will probably have time to toughen his feet, but just keep it in mind. Might save you some trouble down the trail.
