EASY TO USE: Adjust the collar so it fits snugly around your dog’s neck (collar is body heat activated). Keep the collar on your dog at all times. Replace every 4 weeks.

ADJUSTABLE: The ADAPTIL Small Collar fits dogs with necks between 13.2 and 37.5 cm (5.2 and 14.7 in), weighing up to approximately 15 kg (35 lb).

VETERINARIAN RECOMMENDED: Use an ADAPTIL Calm On-the-go Collar to help your dog feel calm and comforted during thunderstorms, fireworks, boarding, training and when facing fears outdoors.

HOW ADAPTIL WORKS: Mother dogs communicate with their puppies through natural messages released in the air. These “comforting messages”, called dog appeasing pheromones, provide a strong signal of security and comfort to dogs of all ages. ADAPTIL Calm On-the-go Collars send a copy of these messages to help your dog feel calm and confident in stressful situations.
