Diagnosis

Canine Pemphigus Foliaceus

This case is most consistent with Canine Pemphigus Foliaceus because the dog has pustules, facial crusting, footpad involvement, and biopsy evidence of autoimmune skin disease. The most important clues are the lesion distribution and superficial pustular pattern, which make bacterial folliculitis less likely.
