When in the US, you should expect breeders to follow the OFA regulations; if the breeder lives in Canada, they should follow the OVC regulations (and note that a number of Canadian breeders do OFA rather than OVC); and if in Germany, they should follow the SV regulations (also note, the SV does not yet
require elbow certifications, but they are researching the need for this).
Voluntary registration of individual Bouviers in CHIC currently
requires certification of testing for hip and
elbow dysplasia, cardiac exams, and eye exams through OFA, PennHip, and CERF.
