The Beaphar CaniComfort Calming Collar Puppy is a simple and effective solution to help calm, comfort and reassure puppies, and help reduce unwanted behaviour. Beaphar CaniComfort contains a copy of the naturally produced Dog Appeasing Pheromone, which is instantly recognisable to puppies. It is naturally produced by the bitch when she nurses her puppies, and is a crucial part of the bonding process. By using a copy of this pheromone in the Beaphar CaniComfort Calming Collar Puppy, it gives a continuous and reassuring message to help puppies feel at ease wherever they are. This can be incredibly valuable when bringing home a new puppy, helping them settle quickly into their new routine. Once fitted, the collar works quickly and will start creating a calming effect around 15 minutes after application. The collar will be effective for up to four weeks, meaning it is ideal for helping to keep your puppy calm when out and about, and is especially useful when attending training classes, travelling or during socialisation. The collar must be fitted at least 15 minutes before a potentially stressful situation. Your puppy's body temperature will activate the collar, diffusing the pheromones into the air and creating a calming effect. Suitable for all breeds of puppy.
