?Tollarsjuka? is a disease with a suspected immunopathological background seen in Nova Scotia duck tolling retrievers. Pyrexia, lameness, stiffness and joint- or musclepain are typical clinical signs. The purpose of this study is to describe case histories from dogs with a possible evidence of ?Tollarsjuka?. 18 private dogs were included in this report. Generalised stiffness, lameness and fatigue were the most frequent manifestations of the disease.

Hundrasen Nova Scotia Duck Tolling Retriever (Tollare), en apporterande ras med ursprung i Kanada, var i början på 1900-talet nära att utrotas på grund av två epidemier av valpsjuka som härjade i landet. I dag har rasen rapporterats vara predisponerad för vissa immunmedierade sjukdomar däribland s.k. Tollarsjuka. Tollarsjuka används i dagligt tal och är egentligen ett samlingsbegrepp för två olika immunmedierade sjukdomar: en SLE (systemisk lupus erythematosus)-liknande reumatisk sjukdom samt en aseptisk meningit. Vid den reumatismliknande sjukdomen ses stelhet i leder och vandrande hälta som går i skov.

In the dog breed Nova Scotia Duck Tolling Retriever (NSDTR) several dogs suffer from joint pain and possibly pain from the muscles. This diffuse disease is called Immune-mediated Non- Erosive Arthritis in Nova Scotia Duck Tolling Retriever. The disease is most likely of autoimmune nature where the etiology still is unknown. The musculoskeletal symptoms of stiffness and shifting lameness are intermittently seen. Some dogs also have dermatological changes and some dogs suffer from pain when opening their mouth. The study included 20 diseased and 20 healthy NSDTR. The purpose was to describe immune-mediated arthritis in NSDTR based on symptoms, results of analysis and effect of treatment. Among the diseased dogs 65% had serum positive for antinuclear antibodies by indirect immunofluorescense (IIF) ANA-test.
