Correction to: Breed susceptibility for common surgically treated orthopaedic diseases in 12 dog breeds

Correction to: Acta Vet Scand (2019) 61:19 10.1186/s13028-019-0454-4

After publication of our article [1] we were notified that due to an error in the excel formula used to summarise the control population, the ID-registry data from the Swedish county Gävleborg was not included in the calculations. When including Gävleborg, as intended, the numbers in the adjusted Swedish control population change slightly. It does not influence the Norwegian control population.

The correct Tables 4 and 5, as well as the correct version of Additional file 1 are included in this correction.
