I got a second hand dog, when she was three. She'd been with a family that spoiled her rotten. She's a Mudi (everyone just said "what?") which is a Hungarian herding breed. They make great watch dogs and are extremely smart. She was obedience trained, so knows basic commands, but she does not respond to toys, does not fetch, and does few things other dogs do…. The breeder got her back when her family lost their house and could not keep her. The breeder emphasized that with this breed, I cannot allow the dog to take charge, or I would end up with the kinds of behavior the previous family had – she and her sibling would herd all the local children around the neighborhood. Other people will tell her to do things, and she ignores them completely. Rather than greeting others, she warns me about them. It's taken a long time to get her to accept people I hike with. Definitely not anything like a lab or golden.
Shortly after she came to me, she dug out of the yard and I came home to find her sitting on the front porch. I'm sure she had some excellent adventures. She lives to walk – at the drop of a leash she gets mega excited. So hiking is just another walk. She's right under my hammock or just outside the tent door while I'm sleeping.
One of the things the breeder did that paid off hugely for me was exposing her to many sensations and experiences early. I walked her into the sports store and tried dog packs on her – she was nervous of the store, but let me put several packs on her. The breeder had put costumes, packs and harnesses on all her puppies, and I can put anything on her now. One of the best things is the Ruffwear Roamer – the leash is either a shorter one with a waist belt, or a longer one with a hand loop (adjustable) and it's long enough to be her tie-up in camp. She has a fleece jacket for when temperatures plunge, which she loves – her hair isn't thick enough to insulate so well and she dislikes cold. She isn't a roamer and has a pretty reliable return – when a friend's dog chased deer and she charged after, she came back when called. (She doesn't seem to have a strong prey drive, luckily).
I make a mix of brown rice and turkey burger and dehydrate it for her trail meals. It makes being on the trail a different experience, since she gets high quailty non-corn-based kibble at home and never our food. She comes to sit and wait when the stove comes out and the boiling starts. I have also given her cooked, deboned trout (never raw – salmonids can have a parasite that's deadly to canids, which is why she never gets to wander around lakes where fisherman casually dispose of guts) and also bring some favorite dog treats (people giving her jerky caused some concern when she started vomiting after hikes. No jerky, no upchuck.). She carries her food, her dish, her booties, a few first aid items specific to her, and her ccf pad strapped along the top of her pack. We bring couple of poop bags for frontcountry areas on the way to the trailhead (long drive, potty stops),
I also keep her from wandering where many have camped. Feces are never buried quite deep enough. Dogs get giardia, too.
