The aim of this study was to verify the usefulness of the measurement of chosen cardiovascular activity parameters for examination of sex pheromones effects in male dogs. We evaluated the influence of the bitches’ sexual pheromones (BSP) on heart rate (HR) with the use of a Holter monitor, and chosen parameters of blood flow in vessels of penis, testes and kidney, with color-coded and pulsed Doppler ultrasonography. We found that the BSP increased HR in all examined males even without showing any other signs of arousal. There were no changes in the RI (resistant index) and PI (pulsative index) in any trials during the pheromone presentation. The increase in blood flow intensity was noted in penile vessels but not in the testes and kidney. We concluded that measurement of flow intensity in the penis as well as the changes in heart rate as the male’s reaction to the BSP can be useful in research concerning sex pheromones in dogs.
