Changes in routine, time alone, or loud events can be stressful for dogs and may be associated with barking, fear, or restless behavior. This diffuser is made to provide a steady pheromone-based signal in the home, supporting a more comfortable setting during everyday stress and specific situations such as thunderstorms or fireworks.

What comes with the diffuser, and how long does it last?

The LKBHGF kit contains one plug-in diffuser head and three tasteless 48 mL refills, with a 90-day supply overall. The refill formula uses gentle ingredients, and the kit is designed to keep pheromones available in the home over an extended period.

• Four-piece kit: one diffuser head plus three refills.
• The refills are tasteless.

How does the pheromone diffuser help dogs feel calmer?

The diffuser imitates pheromones associated with a mother dog’s care, sending signals intended to help dogs feel safer and more comfortable. It is designed to support dogs experiencing stress or fear rather than act as a sedative. The brand’s performance claim is that its pheromone technology helps 90% of dogs feel calmer within two weeks; veterinarians recommend the diffuser.

• Designed to support a relaxed environment and comfortable sleep.
• Made for anxiety-related behaviors such as barking, aggression, and fighting.

Where should I place the plug-in diffuser?

Place the LKBHGF diffuser in a ventilated area where your dog spends most of its time; its stated coverage is up to 700 square feet. Keeping it clear of enclosed or blocked spaces helps the pheromone diffuser function in the room.

• Avoid placing it under shelves, behind doors, or beneath furniture.
• Choose an area with airflow rather than an unventilated location.

This kit suits dog owners looking for a home-based way to support pets during separation, traffic, travel, veterinary visits, loud noises, fireworks, or thunderstorms. It is intended for dogs experiencing stress-related situations, and its plug-in pheromone design provides a continuous calming presence within the covered area.
