- Product Details
Stronghold 240mg for dogs is for the treatment and prevention of flea infestations, ear mites, heartworm, roundworm, hookworm, biting lice, and sarcoptic mange.
Stronghold is a ‘colourless to yellow’ ready to use solution of Selamectin – the active ingredient used to protect your pet against ectoparasites and endoparasites.
Stronghold 240mg for dogs is available in either 3 pipette or 6 pipette packets. Each pipette is enough to treat a dog weighing between 20.1 – 40.0kg and should be applied to the skin on the back of the neck once every four weeks. However, your veterinary surgeon may advise to apply it more or less regularly.
Stronghold is only available in the UK with a veterinary prescription. Stronghold 240mg for dogs comes in a green coloured box with a golden retriever on the front - each pipette will also have a green coloured cap.
Please note that Stronghold 240mg for dogs does not cover against tapeworms. It is recommended to also use a wormer such as Drontal Plus Flavour Bone and Drontal Plus Flavour XL alongside Stronghold to cover your animal against tapeworms. Drontal should be given every 3 months.
Stronghold is also available in the following forms ; Stronghold Puppy & Kitten, Stronghold Toy Dog, Stronghold Small Dog, Stronghold Medium Dog, Stronghold XL Dog and Stronghold Cat.
Do not use in animals under 6 weeks of age. Do not use in cats.
This product is to be applied to the skin surface only. Do not administer orally or parenterally.
Do not apply when the animal’s hair coat is wet. However, shampooing or soaking the animal 2 or more hours after treatment will not reduce the efficacy of Stronghold.
For ear mite treatment, do not apply directly to the ear canal.
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.
