Go to Sök hundar in the left menu and search by Regnr, tatoo, chipnr, name, breed, sex. “Sök” is the Search button.
E.g. for dogs from 1970 and onward enter in the field Regnr: S*/70. In the result list click on a regnr takes you to the chosen dog.
Link to the Swedish Online Database
On the start page there is a link to Avelsdata, where you can use health information as search parameter, e.g. all HD free dogs of 1999. Unless you need a specific search, the above link will do, as there is also a tab with the health results included.
