>>1828449I like hiking alone without a dog, it is liberating being alone and free in the middle of the woods anon. Although I am getting a dog soon, I miss having a battle buddy to love/talk to and not go crazy when I am alone for a week straight.
As for food, it depends. Mountain pantry makes good freeze dried stuff (pic related is cash but fucks up my tummy), but if you are just going on a short hike (a few miles? under 10?) just bring snacks and water. Really depends on the person.
