Our pet perfume Roller contains valerone, rosewood and mint leaves. It can increase natural pheromone levels, relax your pet's mood, be gentle and non-irritating, and build a positive relationship with your pet. Its use is simple: apply the product evenly on the arm or wrist, etc., for fragrance. When pets smell it, they are attracted to it. Sandalwood, citrus, and mint have a calming effect on dogs and help reduce their anxiety. Increase attraction and make your dog like you more.
