In writing my thesis on " Breeding, hunting caracteristic and trening golden retriever", I have studied the concept of cinology more closely and furthermore its importance in dog reproduction, both hunters and helpers, and their psychological importance to humans. Through past and dog domestication, up to today's FCI standards and all cynological regulations, I investigated all types of retrievers and kept on studying golden retriever breed standards. Their body composition and the susceptibility to illness are described more closely, which is unfortunately more and more due to breeders who do not tolerate their genetic predisposition. The great importance of golden retrievers is in their hunting characteristics, which are genetically predestined and are successfully perfected through training. The last part of the thesis deals with the training of hunting dogs, rules and tests to determine the dog's ability for a specific task for which he is trained and intended
