Pyoderma in dogs is a common bacterial skin infection that often causes itching, redness, pustules, and hair loss. It usually develops when bacteria infect damaged or irritated skin due to allergies, parasites, or wounds. Veterinarians typically diagnose it through skin examination and laboratory tests. Treatment depends on severity but often includes medicated shampoos, topical therapies, and antibiotics such as cephalexin capsules to control the infection. Maintaining proper hygiene, balanced nutrition, and regular vet checkups helps prevent recurrence. Early treatment is important because untreated pyoderma can spread deeper into the skin, making recovery slower and more complicated for affected dogs.
