Dog appeasing pheromone
Dog Appeasing Pheromone (DAP) is a chemical developed to calm dogs suffering from separation anxiety disorder, astraphobia (fear of thunder and lightning), fear of fireworks, or those with excessive barking problems.
The chemical is a synthetic analogue of a hormone produced by nursing canine mothers that is seen as 'promoting calm and secure behaviour and in establishing a bond with the mother.'
A randomized clinical study published in 2008 examined the effects of DAP on puppies enrolled in socialization classes. The study found that puppies receiving the hormone exhibited less anxiety and more positive interactions with other puppies than those receiving placebos. A double-blind, placebo-controlled study published in 2007 analyzed its effects on newly-adopted puppies aged 6 to 10 weeks; it found that DAP treatment induced a statistically significant reduction in crying among gun dogs only, and did not influence soiling.
