Moab, my 15 year old pal, has been on several trips with me and absolutely will not eat dog food on the trail. Moab eats dog food at home exclusively. One time she went three days without eating any dog food on a trip. As a result, maybe she is smarter than I think, she eats the same meals I do on the trips. Not only is "human food" lighter than dog food, but I imagine it tastes better. I am not a vet, so take my advice with a grain of salt, but Moab eats Lasagna, Chili Mac, etc. and loves it! Go figure!
