D.A.P stands for Dog Appeasing Pheromone. The ‘appeasing pheromone’ is naturally released by all lactating mammals to comfort and reassure their offspring. DAP® is a synthetic copy of the natural canine appeasing pheromone proven to help support dogs in a range of stressful situations. The efficacy of DAP® has been demonstrated in 18 studies published in scientific journals and at veterinary conferences around the world.
