Yellow Snow Experiment

While talking Jethro on his daily walk I conducted a study of his sniffing and urination patterns. To learn about the role of urine in eliciting sniffing and urinating, I moved urine-saturated snow ("yellow snow") from place-to-place during five winters to compare Jethro's responses to his own and other dog's urine. Immediately after Jethro or other known males or females urinated on snow, I scooped up a small clump of the yellow snow in gloves and moved it to different locations. For some reasons passers-by thought I was strange and generally left me alone. Moving yellow snow was a useful and novel method for discovering that Jethro spent less time sniffing his own urine than that of other males or females.
