Biewer terrier was connected to the PEVISA-program (a programme to oppose hereditary illnesses in the breed in Finland) at the same time it was accepted by the Finnish Kennel Club. PEVISA includes offical knee and eye checks. Without these examinations done to the parents, you can't register the litter to Finnish Kennel Club. Results of these examinations are available for all to see in the Kennel Club's system. 

Biewer terrier is a quite healthy breed.
