The Beaphar CaniComfort Calming Collar Adult is a simple and effective solution to reducing problem behaviour in dogs, such as barking, furniture destruction, urinary marking, excessive licking and scratching, or general feelings of anxiety. Beaphar CaniComfort contains a copy of the naturally produced Dog Appeasing Pheromone, which is instantly recognisable to dogs. It is naturally produced by the bitch when she nurses her puppies. By using a copy of this pheromone in the Beaphar CaniComfort Calming Collar Adult, it gives a continuous and reassuring message to help dogs feel at ease wherever they are. This can be incredibly valuable when bringing home a new dog, 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 dog calm when out and about, and is especially useful when travelling or spending time in kennels. The collar must be fitted at least 15 minutes before a potentially stressful situation. Your dog's body temperature will activate the collar, diffusing the pheromones into the air and creating a calming effect. Suitable for all breed of dogs.
