Everything about this dog is conscientiously crafted by independent producers, from the nitrate-free dogs to the naturally cultured small-batch kraut and artisan gouda cheese.
Heat grill to medium (350° to 450°). Grill dogs until slightly charred all over, about 6 minutes, turning occasionally.
Meanwhile, cut pretzel buns horizontally partway through. Sprinkle cheese into buns, dividing evenly; then grill buns until warmed, lightly charred, and cheese has mostly melted, about 4 minutes.
Spread mustard inside buns, add dogs, and top with sauerkraut.
