Remove the Stronghold tube from its protective package. Holding the tube upright, firmly depress the cap to puncture the applicator seal, then remove the cap. Part the hair at the base of the animal’s neck in front of the shoulder blades to expose a small area of skin. Apply the tip of the Stronghold tube directly to the skin without massaging. Squeeze the tube firmly to empty the contents in one spot. Avoid contact between Stronghold and fingers.
