Directions For Use

Remove one tube from the package by tearing along the serrations. Leaving the plastic tube attached to the cardboard backing, hold the tube upright and cut along dotted line. Invert the card over the dog and use the point of the card to part the hair of the dog at the application site. Squeeze the tube firmly to apply the required dosage of the solution. To be effective, the product must be applied directly on the skin, not on the hair. Correctly dispose of the tube. (See DISPOSAL).

For mosquitoes: Apply only when mosquitoes become a nuisance for the pet. The product should reduce mosquito bites for up to a month, but some factors such as bathing or swimming may reduce the duration of effectiveness. Do not apply at intervals of less than 7 days.

For lice: If the product is used specifically for lice, apply only when the pest problem occurs on the pet. Treatment should only be repeated if the pest problem persists or reoccurs but do not apply at intervals of less than 7 days.

Dosage for dogs weighing 15 kg (33 pounds) or less: Apply 1 mL to the dog’s back between the shoulder blades.

Dosage for dogs weighing 15-30 kg (33-66 pounds): Apply 1 mL to the dog’s back between the shoulder blades and apply 1 mL to the dog’s back to the area at the base of the tail.

Dosage for dogs weighing more than 30 kg (66 pounds): Apply 2 mL to the dog’s back between the shoulder blades and apply 2 mL to the dog’s back to the area at the base of the tail.

GENERAL: Defend® is an effective and easy to use product. Defend® demonstrates greater than 95% control of fleas and ticks within 3 days of application. One application controls fleas and ticks for up to one month. It may be desirable to use knockdown agents or remove attached ticks at time of treatment. Defend® is not an organophosphate. Defend® has been shown to have a wide margin of safety in dogs and may be used on any breed of dog. As with all flea and tick control products, Defend® should be used as part of a control program aimed at reducing flea populations in the dog’s environment (bedding, carpets, kennel, yard). Consult your veterinarian or entomologist for program recommendations. Defend® reduces mosquito bites within one day of application. Defend® has shown control of lice infestations within 7 days of application.
