Powered by Mother-Scent Pheromone Technology
Our diffuser releases a gentle pheromone that mimics the natural calming scent produced by mother dogs. When puppies smell this scent, it signals safety and comfort in the brain.
By recreating this familiar signal in your home, the Only Relief diffuser helps dogs feel relaxed and secure — reducing stress from separation, loud noises, and unfamiliar situations.
The result is a calmer dog and a more peaceful home, 24 hours a day.

Frequently Asked Questions
Pheromones are a mixture of fatty acids. Our products also contain a solvent, which helps dissolve the pheromones so they can be sprayed or diffused.
The plug-in should be used in rooms where your cat spends most of its time. Avoid using outlets that are under windows, near air vents or close to doors as drafts will impair the ,proper diffusion of the pheromones. DO NOT plug the diffuser into a power strip or surge protector. The vial should always be directly below the plug-in unit for proper diffusion and to prevent leakage. To ensure the vial is always below the plug-in unit, there is a swivel function on the prongs for outlets with horizontal orientations.
For the diffuser, you will start to see your dog become calmer and more relaxed over the course of at least 30 days of continuous use.
The pheromones are diffused when the plug-in unit heats up. As with any heating element, a slight smell may be present and is totally normal. If you find your diffuser has a stronger smell, please call us and we will be happy to troubleshoot with you!
To keep the good vibes flowing, you should keep your diffuser plugged in at all times. If you notice your diffuser collecting dust, please unplug and follow the cleaning instructions in the user manual found in every box.
We recommend replacing the refill vial every 30 days or when the liquid runs out. The plug-in unit should be replaced after 6 months of use or after you have used three refill vials (whichever comes first!)
