Describe intertrigo pyoderma
Skin moist, greasy, erythematous, hyperpigmented +- whitish maloderous exudate
Affects skin folds
Surface pyoderma
Variably pruritic
Describe impetigo pyoderma
Common in young dogs (3-5m) & dogs suffering from immunosuppression (can have large pustules)
Composed of interfollicular pustules

Infection & inflammation within dermis –> deep pyoderma
Not always pruritic but can be very painful

How is impetigo treated?
Topical chlorahexidine shampoos/foams
Systemic first-tier antibiotics if topical treatment not possible/ineffective
Treat to 1 week post clearing (likely 2-3w total min.)
How is folliculitis treated?
Topical chlorahexidine shampoos/foams

How is furunculosis treated?
