I used to have two dobies that I took on every trip, wilderness or otherwise, with there own packs. Only way to go on a week long trip. Non-aggressive dogs when out or at home. Although my male got protective at one campsite and stood between me and some hikers on the trail above us and barked a little. My late dog, Pooch, a Yellow Lab X was a excellent pack dog. I took him everywhere as well, which prevented me for years from going into Lassen or Yosemite parks. He stayed close on the trail and in camp. A great bear dog also. In his life, I only heard him bark about four times, three of those times at bears. He was partially trained in SAR also. A great moment the first time he "alerted". What a feeling. Very trusting dog, on one bp trip, he had to come down a narrow chute to me, which was nearly vertical for 10'. With no hesitation, he piled down. Big hugs after that. I lost him to a bleeding cancer at around 11 years of age.:(

Edit. Pooch was a rescued dog from the animal shelter by a vet.
