Endorsed By VETs & Behaviorists

TheraPet Diffuser is your effortless solution for a more relaxed, happier dog. It diffuses a natural, calming scent—known as pheromones—that only dogs can detect. These pheromones are like comforting messages, assuring your pup, "You're safe and loved."

TheraPet helps reduce stress-driven behaviors like barking, peeing, chewing, and scratching, granting your home—and your pup—a sense of tranquility. It's like whispering soothing words to your furry friend, throughout the day, every day!

Setup is quick—after that, TheraPet runs on autopilot.

  • Pick an open outlet in your dog’s favourite room
  • Twist the refill vial into the diffuser until snug
  • Plug in and leave running; replace the vial every 30 days for continuous calm

A unique pheromone blend you won’t find in any other diffuser.

  • Combines pheromone signals for a broader calming effect
  • Delivered in a plant-based carrier—no added fragrance or alcohol
  • Heat-controlled diffuser ensures steady, even release for 30 days

Keep the calm constant and spend less while you’re at it.

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.
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 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.
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!)
