| Abstract: | Male dogs were given five separate two-way olfactory preference tests in which control urine from males was compared with: estrous urine; 75% estrous urine + 25% male urine; 50% estrous urine + 50% male urine; 25% estrous urine + 75% male urine; and 25% estrous urine + 75% water. The stimulus value of estrous urine was progressively decreased by the addition of increasing quantities of male urine. However, estrous urine still maintained a high stimulus value when it was diluted with an equivalent amount of water. |
