[The evaluation of breed-specific defects in dog breeds from an animal welfare viewpoint].

Issues of breed defects such as morphology, physiology or behaviour in pure-breed dogs, are briefly discussed. Suggestions for various kinds of improvements are made, particularly concerning legislation, analysis of pedigree to avoid undesirable breed characteristics and what breeding clubs, individual breeders, judges, future dog owners and veterinarians could and should do about these problems; these are followed by summary conclusions.
