Experience on pedigree control in Swiss pure bred dogs

Each year approximately 13000 new pedigrees for puppies are issued by the S wiss Kennel Club. Except for a few cases there are no regulations to verify the paternities independently. This re port describes the practical proced ure for disputed paternities and summarizes the results from 35 cases which were resolved during the last three years. Most cases relate to unwanted o r wanted double matings. Generally the owner of the bitch can not state the sire. For roughly half of the cases where a sire was given as the parent t he information was disproven by the genetic analysis in the laboratory. The se experiences confirm the need for a better pedigree control in Swiss dog breeds. Breeding without correct pedigree control is restricted to animal k eeping.
