The clinical signs of infection in dogs with Neospora caninum are usually associated with neurological disorders and are seen in young dogs. In this brief case report we observed multifocal ulcerative and exudative skin nodules on the neck and pelvic limbs of a 10‐year‐old cocker spaniel dog. Infection with N. caninum was diagnosed on the basis of cytology and examination of skin tissues by PCR. The dog initially responded to treatment with clindamycin and then relapsed; the dog died. Infection with N. caninum may have been due in part to immune suppression due to hyperadrenocorticism; which either allowed for the development of a primary infection or reactivation of a latent infection by N. caninum with the occurrence of skin lesions.
