TopSum Calming Diffuser for Dogs offers a drug-free approach to help dogs feel safe and comfortable at home. It targets everyday triggers such as separation, loud noises, routine changes, barking, whining, chewing, and indoor accidents, without medical intervention.
The continuous pheromone diffusion technology releases a steady signal designed to support emotional balance. Used as part of a daily routine, many pet parents notice calmer moments over time as the diffuser runs in the background.
Each diffuser covers up to 750 square feet, helping you maintain a consistent calming environment across rooms. The 3-pack value set includes three diffuser heads and three long-lasting refills for extended use and savings.
Ideal for multi-dog homes and daily life challenges. Use when introducing new environments, during visitors, crate training, thunderstorms, fireworks, travel, or routine changes. Safe for puppies and adult dogs when used as directed.
Set up is simple: plug in, keep upright, and enjoy low-maintenance calming support for your dog and home. The purple diffuser head adds a touch of color to your space.
Designed to fit busy households and support peaceful routines, this kit offers a practical, non-invasive option for everyday calm at home.
