Juvenile Cellulitis (Puppy Strangles)

Juvenile cellulitis is an uncommon skin condition that affects young puppies, typically between three weeks and four months of age. It involves sudden inflammation of the skin on the face, particularly around the muzzle, eyes, and ears, often accompanied by swelling of the lymph nodes under the jaw. The condition is thought to involve an immune system response rather than infection, though the exact trigger remains unclear. Owners often notice that their puppy's face has become puffy or swollen, sometimes quite dramatically, with the skin feeling warm or developing small pustules. The ears may also be affected, and some puppies seem uncomfortable or less playful than usual. Despite its dramatic appearance, the condition typically responds well once recognised, though untreated cases can occasionally progress. This page explores what signs may appear, what is understood about the underlying process, how the condition is investigated and distinguished from other causes of facial swelling in young dogs, and what treatment approaches exist.
