Together they have written two books on breeding and keeping German Shepherd Dogs and have published more than 30 articles on the subject. Frikkie has always upheld the Genetic side of things and Sonia the keeping and preparation.

Frikkie has a BSc degree with majors Genetics and Zoology and BSc(Hons) and MSc degrees in Mammalogy. The latter degrees combined Genetics as a basis. He has also lectured Genetics at Pretoria University and the Medical University of South Africa (Medunsa).  

This background makes them uniquely qualified to breed top class poultry.
