This bachelor thesis deals with the special drug detection dogs training and compares various dog breeds. According to the current conditions of Czech and foreign criminalistic odorology this criminalistic technique which uses olfaction of specially trained detection dogs is classified amongst the modern techniques today. The theoretical part describes the origin and the development of the domestic dog, pursued dog breeds, criminalistic odorology, special detection dogs training, dog's sense of smell from the anatomical and physiological point of view, dog handler's job, finding and distinguishing of various odors and general knowledge of odor and scent trails. The practical part evaluates which of the pursued dog breeds is the most effective, the most used and the most successful one in practice. The success rate of dogs according to their age, sex and the active period of service was also found out in the practical part. It was evaluated to what extend does the dogs' training frequency affect the success rate and which method of narcotics detection is preferred. All the data were collected by means of a questionnaire study. It was found out that the most used dog breed for narcotics detection is the German Shepherd, the second most used breed is Belgian Malinois. Of all pursued dogs (74) there were 34 German Shepherds whose success rate was 90,9 % and 23 Belgian Malinois whose success rate was 72, 99 %. It was found out that in 75 % the dogs are better in detecting plant-based drugs such as marijuana/hashish, cocaine, opium, some kinds of poppy seeds, tobacco, nicotine etc. The recommended dog gender is a male dog, the best performance can be expected with 5-6 years old dogs (3-4 years of active service). If the dogs are expected to carry out excellent performances, the training frequency must be adjusted to 7 times a week and the dog must be trained only in one discipline, in this case it is the narcotics detection.
