Every time I've seen people out hiking with dogs, I've thought backpacking with goats would be a lot of fun. I've never been a real fan of dogs and cats, but I think goats could haul a lot of gear, provide companionship without all the silliness domestic pets offer. I get that goats kind of crap everywhere, though they can be potty trained to only pee in specific places. Their barnyard animals, but much more useful I'd argue then dogs for many uses.
