Also helps support dogs experiencing separation anxiety when left home alone. SUITABLE FOR DOGS AND PUPPIES: of all ages and breeds. Pheromones are instantly recognisable to all dogs, even if they were hand-reared. Calms without sedating, and does not affect humans or other animals. The diffuser can also be used alongside other Beaphar CaniComfort products.
