You won’t smell a thing, but your dog will recognize the pheromones.

So your home stays fresh and your pup stays calm — the best of both worlds.

Each refill bottle lasts for about 30 days of continuous use and covers up to 700 sq. ft. of space.

For best results, keep the diffuser plugged in 24/7 in the main room where your dog spends most of their time.

If you have a larger home or multiple floors, you may want one diffuser per main area for consistent coverage.

Yes — the Zellumira CalmDog™ Diffuser is designed to stay plugged in continuously.

It uses low heat and meets all international safety standards for home use.

Just make sure it’s not blocked by furniture or curtains, and let it do its calming magic day and night.

One diffuser covers up to 700 sq. ft., which is usually enough for a single living area or medium-sized apartment.

For larger homes, we recommend one diffuser per main room where your dog spends the most time — such as the living room or bedroom.

That way, your pup always feels surrounded by calm, no matter where they are.

The Zellumira CalmDog™ Diffuser is completely drug-free and safe to use alongside behavioral training, supplements, or prescribed medication.

It works naturally with your dog’s instincts, not against them.

If your dog has a medical condition or is on strong medication, it’s always a good idea to consult your vet before introducing any new product.
