The records of six dogs in which a diagnosis of symmetrical lupoid onychodystrophy (SLO) had been made were examined retrospectively. The age at onset ranged from six months to eight years. All the dogs had been presented with onycholysis, onychomadesis, onychalgia and onychodystrophy. The diagnosis of SLO was confirmed in all cases by histological examination. Histological features were similar in all cases and included hydropic degeneration of the basal cell layer, pigmentary incontinence and a cell‐rich Interface dermatitis. Response (defined as good, partial or failure) to various therapies was compared. Treatments (as initial therapy or following previous treatment failure) included essential fatty acids (EFA) (three cases), a combination of tetracycline and nicotinamide (four cases) and azathioprine and/or prednisolone (one case each). EFA therapy resulted in one good response, one partial and one failure, tetracycline and nicotinamide in two good responses, one partial and one failure, and azathioprine and/or prednisolone In one good and one partial response. Although all treatments were successful in some cases, none was universally effective.
