The dog-driver helped solve Buck's sore feet problem by providing a comfortable resting spot and removing ice particles between Buck's toes.
Explanation:
The dog-driver helped solve the problem of Buck's sore feet by taking off the saddle-bags from the burros, removing the saddles, and letting the burros loose. He then led Buck to a flat space, removed the outer blanket from around Buck, and laid him down on a bed of deep dust. The dog-driver also removed the ice particles that had formed between Buck's toes to prevent further discomfort.
