On physical examination the dog was depressed and had three draining nodules 3.0 to 4.0 cm in diameter on the neck, flank and back. The multifocal sparing of fat lobules, macrophages, and numerous neutrophils were observed in aspiration cytologic examination of nodule. Haematological examination demonstrated a moderate leukocytosis and neutrophilia. An aerobic bacterial culture was undertaken from draining lesions on the flank. But there was no bacterial growth in aerobic culture. Therapy was initiated with oral cephalexin at a dose of 20 mg/kg, body weight three times daily and prednisolone at 1.0 mg/kg twice daily. The (lug returned to normal within 24 hours of treatment and its general attitute and appetite were improved. However, within 1 month new nodules had appeared on the dorsum over the rump, coalescing into a mass of draining nodules and tracts.
