We understand the challenges of stress and anxiety in dogs. Whether it's fireworks, separation anxiety, travel stress or tension around new visitors, we know it can be upsetting for all involved.

That's why we've created the Omni Calming Diffuser - a smart, soothing solution powered by science and inspired by nature.

Its slow-release system mimics the natural pheromones released by mother dogs, sending calming signals to your pup and helping them cope more effectively with triggers.

Ideal for sudden scares and longer-lasting stressors, it's species-specific, drug-free and odourless (so won't effect, you, your cat or your living room). It's safe for all ages and breeds, including puppies and seniors.

Simply plug it in to create an instant canine comfort zone.


Canine Appeasing Pheromone Complex (2%), Isoparaffinic Hydrocarbon (48ml)

Each 48ml vial lasts up to 30 days and spans an area of 700 sq. ft. Before using, please read all instructions carefully.

Plug the diffuser in the room in which your dog spends most of their time. Replace the refill as soon as the vial is empty or after 30 days, whichever occurs first.

When connected to a working outlet, press the purple button to turn the diffuser on. The button will light up on the diffuser
confirming that it’s receiving power.

Our diffuser gently released a synthetic version of the Dog Appeasing Pheromone (DAP) - a natural substance produced by nursing mother dogs to reassure their puppies - into the air.

This pheromone signals safety and security, helps reduce anxiety-driven behaviours and creates a calm environment. Although odourless to humans, dogs can detect it and respond instinctively.
