Juvenile cellulitis (puppy strangles) is a severe inflammatory skin and lymph node condition in puppies under 4 months that causes significant welfare suffering and can leave permanent scarring if inadequately treated.
Juvenile cellulitis causes acute welfare suffering through painful facial swelling, suppurating pustules, enlarged painful lymph nodes, and systemic illness including lethargy and inappetence. Young puppies in the prime of their socialization window are significantly welfare-impaired by this condition — both physically uncomfortable and isolated from normal puppy social experiences during treatment. The critical welfare issue is adequate treatment — puppies treated with antibiotics alone typically develop extensive facial scarring that permanently impairs their quality of life and social acceptance by other dogs. Early recognition and aggressive immunosuppressive treatment with systemic corticosteroids is the welfare-positive approach that produces complete recovery without scarring.
