The ZENIDOG® collar contains canine calming pheromones that help dogs feel relaxed and comfortable in stressful situations. The ZENIDOG® collar is designed for daily use. Once fitted, allow the pheromones to work continuously for 3 months. Its effectiveness is proven, reducing stress-related behaviors by 89% (2). It is safe for dogs and puppies of any age and can also be used in conjunction with a flea and tick collar. The collar is available in two adjustable sizes to ensure the perfect fit: small and medium/large. What are pheromones and how do they work? Pheromones are natural signals that dogs use to communicate and feel safe in their environment. A mother dog nursing her puppies naturally releases these pheromones to convey calm and security to them. ZENIDOG® mimics these maternal pheromones to help calm your dog and reduce stress-related behaviors. 2. Nicolas, CS, Espuña, G., Girardin, A., Fatjó, J., Bowen, J., & Monginoux, P. (2025).
