Adaptil Junior Collar is a pheromone collar for puppies that continuously releases the dog appeasing pheromone (DAP) to support young dogs through early life transitions. It is sized for puppies and provides up to 4 weeks of continuous calming coverage.

The collar is activated by the puppy's body heat and releases pheromones wherever the puppy goes — effective during car trips, puppy classes, vet visits, and introduction to new environments. The DAP pheromone is the same natural signal mother dogs produce to comfort their litters. Odourless to humans and non-sedating.

Early-life pheromone support helps puppies build positive associations with new experiences rather than fearful ones. The collar format means the calming signal is present during the exact moments of exposure — not just when the puppy is at home near a diffuser.
