Analysis of the influence of external factors on olfactory orientation dogs

Presents the results of the study of the influence of climatic factors on the effectiveness of trail work and work on the selection of dogs of the German shepherd breed. The study revealed some intersex differences in the manifestation of olfactory orientation in the considered groups of dogs. Females differed from males greater speed when performing reception "Sample stuff", dogs, opposite had the advantage of time spent on the detection of olfactory track of the person. In summer, males had the advantage of 10.9 and 12.1% over bitches, in the winter - 17.1-36.3 percent. Presumably, this is due to the phenotypic characteristics of dogs: females are more attentive and docile; males are physically stronger and have an advantage when performing work connected with physical activity. Under analysis influence season year established, that the speed detection expands have dogs both gender under lowering outdoor temperature in range from 0 until -6 C, and, contrary, is declining under high year-old temperature (+28ºC), and also under lowering temperature winter until -28ºC. Increase spending time on detecting rights or things reduces effectiveness use of office dogs. The effectiveness of the work is also adversely affected by precipitation and wind of a certain strength. Thus, it was found that with heavy rain, only 12.5% of the studied dogs showed a positive result, with prolonged rain of average strength, correct actions were noted in six dogs, the highest percentage of correct actions of the dog showed with weak rain-14 dogs (87.5%) out of 16 studied.
