Our pet care solution contains chlorpyrifos and glycerin. It can help your dog feel calm and relaxed at home, and can help you and your dog live better together, creating a peaceful environment at home. Its usage is simple: first remove the lid, screw the small bottle into the diffuser unit, and plug it into a power outlet, keeping the diffuser plugged in. After use, reduce the common signs of stress caused by visitors and alleviate the anxiety and fear of staying alone at home, allowing the puppy to calm down and feel at ease.
