The expedition of LEWIS AND CLARK lived and got fat on dog meat back in 1805. They preferred it to horse and deer.
Many an Eskimo dog sled come back with fewer dogs than when it left.
Dog meat was a major staple for many American Indian tribes. It had many advantages over hunting: you always had your meat supply close at hand and instead of traipsing over hill and dale for deer or elk, all you had to do was call "Here Spot" or Indian equivalent, for your dinner BBQ.
"Old Gabe" aka Jim Bridger, king of the Mountain Men, developed a taste for dog meat as did many of the Rocky Mountain trappers of that era. While they preferred "buffalo hump," the fatty part of the bison's back, dog meat was always welcome when they became a mite puckish. When people are very hungry they'll eat anything, including each other. Cannibalism was a terrifying daily occurrence in Stalin's genocide of the Ukrainian Kulaks.
