Johnson's Guardian Plus Spot-on Large Dog

Johnson’s Guardian Plus Spot-on Large Dog combines fipronil and (S)-methoprene to treat fleas, ticks and biting lice. It also inhibits the development of flea eggs, larvae and pupae originating from eggs laid by adult fleas on the treated dog, helping break the flea life cycle.

This pack contains one 2.68ml pipette for one treatment. It is the large-dog size, marketed for the 20–40kg range. The authorised dosing instructions specify dogs weighing over 20kg and up to 40kg; for a dog weighing exactly 20kg, check the supplied leaflet and confirm the correct size with your vet before use.

• Adult flea control persists for eight weeks.
• Inhibits flea egg, larval and pupal development for eight weeks after application.
• Tick control lasts for up to four weeks.
• Treats biting lice (Trichodectes canis).
• One pipette per pack, providing one treatment for a dog in the correct weight range.

Composition

Each 2.68ml pipette contains fipronil 268mg and (S)-methoprene 241.2mg. Other ingredients are butylhydroxyanisole (E320, 0.54mg), butylhydroxytoluene (E321, 0.27mg), anhydrous ethanol, polysorbate 80 (E433), povidone and diethylene glycol monoethyl ether.

How to apply

Weigh your dog accurately before treatment. Use one complete 2.68ml pipette for a dog weighing over 20kg and up to 40kg. Do not overdose or repeat treatment less than four weeks apart.

Hold the pipette upright and tap its narrow part so the contents remain in the main body. Snap back the tip. Part the coat at the base of the neck, in front of the shoulder blades, until the skin is visible. Place the tip on the skin and squeeze several times to empty the whole pipette directly onto the skin in one spot. Apply where your dog cannot lick it, and do not let animals lick each other after treatment. Do not apply to wounds or damaged skin.

Suitability and precautions

For external use on dogs only. Do not use in cats, ferrets, rabbits or other species. Do not use on puppies under eight weeks old, sick or convalescent dogs, or animals allergic to any ingredient. The large-dog weight restriction must also be met. The authorised information permits use during pregnancy and lactation.

Do not use simultaneously with other flea products applied directly onto the animal. Avoid bathing or immersion for two days after application, and avoid bathing more than once a week. Frequent shampooing can reduce the duration of flea protection. Keep your dog out of watercourses for two days after treatment.

Some ticks may still attach, so tick-borne disease transmission cannot be completely excluded. Fleas are killed within 24 hours and ticks and lice within 48 hours after exposure; this is not an instant tick-repellent barrier.

Avoid contact with the animal’s eyes. If contact occurs, rinse immediately with plenty of water. Contact your vet if adverse reactions occur, including skin irritation, excessive salivation, vomiting, breathing symptoms or unusual behaviour or movement.

Handling and storage

Do not handle your dog or let children play with it until the application site is dry. Apply in the early evening and do not let recently treated animals sleep with owners, especially children. The alcohol carrier can affect painted or varnished surfaces and furnishings.

Avoid contact with your mouth, skin and eyes. Do not eat, drink or smoke during application. Wash hands after use and wash accidental skin contamination with soap and water. Rinse accidental eye contact carefully with clean water; seek medical advice if irritation persists, taking the packaging. People allergic to insecticides or alcohol should avoid contact.

Keep pipettes in the original packaging until use, out of children’s reach, and dispose of used pipettes promptly. Store in the original package at no more than 30°C. Follow local disposal requirements and do not contaminate waterways.

Vacuum your dog’s resting areas regularly and use a suitable household treatment when needed as part of flea control. Always read the supplied packaging and leaflet before use.
