Important information
Safety Information
For use ONLY on dogs. Toxic to cats. Cats that actively groom or engage in close physical contact with recently treated dogs may be at risk of serious harm, including death. Sensitivities may occur after using any pesticide for pets. Smaller animals are more likely to experience an adverse reaction. Observe carefully.
Directions
Please remove the collar prior to application. The dog should be standing for easy application. Part the hair on the dog’s back between the shoulder blades until the skin is visible. Place the tip of the tube on the skin and squeeze the tube to completely empty the contents directly on the skin.
