When new pups are born, their mother naturally emits pheromones that give the puppies a sense of security and comfort. These pheromones help dogs bond to each other and their mom. ThunderEase replicates these pheromones for a drug-free, vet-recommended, calming solution that puts an end to unwanted behaviors like destructive chewing and problem barking. ThunderEase is effective in treating: – Fear of loud noises like thunder and fireworks – Uneasiness in a new home or environment – Stress when socializing or during training – Problem barking – Destructive chewing – House-soiling (or “uh-ohs” as we like to call them). – Changes in the environment like new furniture or remodeling. Plug your ThunderEase Calming Diffuser in the room your dog spends the most time and watch the difference in behavior. Improvement may be seen as early as one week, but we recommend using the product for a full month for best results. Replace refills every 30 days for maximum calming benefits.
