📝 Product Details
Product description





How do I know if the diffuser is on?
Press the small yellow duckbill to start our product. Once started, the light blue indicator will turn on. After running for a while, the diffuser feels the slight warmth, which means it’s working properly.
How does the dog diffuser do its job? Soothe the dog?
Yingsu dog calming diffuser releases pheromones mimicking the natural pheromones emitted by mother dogs to calm dogs, creating a sense of safety and comfort similar to that when they are in the presence of their mother.
How long does it take to see results? Why I don’t have visible results after a week of use?
Dog pheromone calming diffuser kit should be used continuously for 2-4 weeks to improve your dog’s anxiety and restlessness, or longer if the symptoms are more severe, depending on the dog. The exact duration may vary from dog to dog.
My dog likes to spend time by the window, would better ventilation help alleviate his symptoms?
The dog calming diffuser should be used indoors. When using it, try to close the doors and windows to prevent ventilation, so as to avoid the situation where the emitted pheromones have a low effect due to the air circulation.
What is supposed to happen when you press the duck bill?
When the duck bill is pressed, the switch of the diffuser will open, the pale blue light will come on, and the equipment will start to work normally.
