Androstenone can stop dogs from barking and jumping. Androstenone is produced by pigs in their saliva or fat, but Boar Mate androstenone is synthesized in a laboratory. One spray of Boar Mate on dogs is all it takes to fix their behavior.
Commentary not seen in article: It's very interesting that pig pheromones can stop dogs from barking, but because it doesn't last very long, it seems very similar to the effect of citronella collars. Why would you choose one over the other? Training may be better solution than constant spraying.
