Usage Instructions:
Weigh the dog carefully before application to ensure it weighs more than 20 kg. Do not remove the tube from the packaging until the product is ready to use. Hold the tube upright, and cut off the top of the tube. Part the dog's fur between the shoulder blades, and apply the contents of one tube to the skin surface, half between the shoulder blades and half at the base of the head.
