Adaptil Calm Pheromone Diffuser and Refill for Dogs is a plug-in device that releases a synthetic copy of the dog appeasing pheromone (DAP) into the home environment. It suits households managing noise phobias, separation anxiety, or general nervousness in dogs.

The diffuser plugs into a standard power outlet and covers approximately 70 square metres for up to 30 days per refill. The DAP pheromone is odourless to humans and other animals and works continuously in the background. The starter kit includes the electric diffuser and one 48ml refill vial. Effective for fireworks season, thunderstorm anxiety, and settling newly adopted dogs.

Adaptil is the most widely recommended pheromone product for dogs in Australian vet clinics, and the diffuser format works best for anxiety centred on the home environment — separation distress, noise phobias, and settling into a new household.
