I tried this once. It actually dried pretty well, though in order to get it to soak up all the water when I re-hydrated it I had to use the microwave, which kind of defeats the raw thing... I put my raw mix of ground meat, eggs, vegetables, and milk (among other things) in a thin layer in the dehydrator at 155 degrees, then crumbled it up. Do use the plastic catcher thing that comes with the dehydrator- you will not ever get it off the racks! It takes a lot more effort that just freezing and thawing, though for trips it would be nice. For all the time you'd save I'd say just go with Honest Kitchen Embark. It's expensive, but if your dogs will eat it it's a whole lot easier than making your own, plus it re-hydrates a lot better. A thought just now popped up in my head- what if you put the homemade dry food in a blender to make the pieces smaller? Might re-hydrate better that way. Hmm...
