The processes involved when a dog sniffs lead to an increase in lung capicity which in turn, leads to more oxygen absorption. This stimulates blood circulation, increases the flow of salvia and leads to an accelerated metabolism. The stimulation of the Jacobson´s organ, situated in the cavity of the dog, results in hormon being released. This combination of activated hormons, a sensitised nervous system, and accelerated metabolic activity promotes the dog´s feelings of well-being and reduces stress. Mellowed, relaxed dogs are able to cope with the challenges of every day life with easy as are their owners.
