A pheromone (from Ancient Greek φέρω (phérō) 'to bear' and hormone) is a secreted or excreted chemical factor that triggers a social response in members of the same species.

Our human olfactory sense is one of the most phylogenetically primitive [ 1 ] and emotionally intimate [ 2 ] of the five senses ; the sensation of smell is ...
A deeper understanding of the physiological mechanisms and the phases involved in canine scent tracking has allowed humans to utilize this animal behaviour in a variety of professions. [2] Through domestication and the human application of dog behaviour, different methods and influential factors on tracking ability have been discovered.
Fear is helpful when it aids the animal in escaping from dangerous animals or catastrophic events. In these cases, it can be said that fear is “adaptive,” as it increases the chances of survival.
Some physiological changes also occurred including the decrease in body weight gain and adrenal hypertrophy observed in animals exposed to stress. Overall, the conditioned fear responses can contribute to behavioral changes in a repeated stress paradigm. This can be extended to correlate to other animals as well but with varying degrees of ...
A study titled "The odor of an unfamiliar stressed or relaxed person affects dogs' responses to a cognitive bias test" was published in Scientific Reports on July 22, 2024, and the results are ...
