Some volatile constituents of female dog urine

Abstract

The volatile compounds from female beagle urine, across the state of estrus, were examined by headspace gas chromatography and mass spectrometry. The major constituents identified were methyl propyl sulfide, methyl butyl sulfide, and acetone. Nine minor constituents, including trimethyl amine and five disulfides, were identified. Two of the unidentified minor constituents may possibly be associated with the state of estrus.

The Efficiency of Synthetic Sex Pheromones in Sexual Arousal Stimulation in Domestic Dogs

“…H5501; Sigma-Aldrich ® , Saint Louis, MO, USA) in their study also stated that "there was no sexual behavior observed between the dogs and the bitch (....), even though she was impregnated with artificial pheromone". Other authors evaluating the composition of canine urine did not confirm the presence of methyl paraben at all in the collected material (Schultz et al 1985, Dzieciol et al 2014.…”

Female Canine Sexual Behavior

“…9,10,17,53 Over half of males are unsuccessful. 137 Both of the sulfides are somewhat higher during proestrus and estrus than during metestrus or anestrus. 79 Once the tie occurs and the male dismounts, the bitch may remain standing quietly, pull against the tie, or forcefully throw the male off balance.…”

“…51 While the male mounts, the bitch stands quietly with her tail flagged to one side. 137 20 this twisting and turning usually lasts 5 to 30 seconds, and the female may actually roll over once or twice.…”

Feeding Responses to Predator‐Based Repellents in the Mountain Beaver (Aplodontia Rufa)

“…Sulfur-containing compounds are ubiquitous in urine, feces, and anal sac fluids of carnivores and are widely aversive to herbivores. Urine and feces from canids and felids contain a number of sulfur compounds, in many cases methylalkyl or methylaryl sulfides (red fox, Vulpes vulpes: Jorgenson et al 1978, Bailey et al 1980, Vernet-Maury 1980wolf, Canis lupus: Raymer et al 1984;coyote: Murphy et al 1978, Schultz et al 1988; domestic dog, Canis familiaris: Schultz et al 1985;bobcat, Felis rufus: Mattina et al 1991;domestic cat, Felis cattus: Mattina et al 1991;lion, Panthera leo: Abbott et al 1990). Anal sac fluids from mustelids (Andersen and Bernstein 1980, Crump 1980a, b, Sokolov et al 1980, Schildknecht et al 1981, Brinck et al 1983) and hyaenids (Wheeler et al 1975, Buglass et al 1990) also contain sulfur constituents, among them heterocycles such as thiolanes and thietanes.…”
