Juvenile pyoderma (also referred to as “juvenile cellulitis”, “juvenile dermatitis” or “puppy-strangles”) describes a pyogranulomatous condition affecting young dogs, generally within the first 6 months of life.Clinical symptoms comprise variable combinations of symmetrical pustular dermatitis of the muzzle, face, periocular tissues and/or ears as well as external ear canal inflammation and/or regional (submandibular) reactive lymphadenopathy.In some cases, more generalized dermatitis may also be present.The disease is postulated to be an immune-mediated reaction, however secondary bacterial infection is common.Commonly affected breeds include the Golden Retriever, Labrador Retriever and Dachshund.
