What is Stronghold Flea Treatment?
It is available as a spot-on solution in 2 different concentrations (6% and 12%) and in tubes of various strengths (15, 30, 45, 60, 120, 240 and 360mg). The concentration and the strength to use depends on the weight and species of the animal being treated. The correct concentration and size will be determined by your vet during their examination of your pet and stated in their written prescription.
Stronghold Spot On is primarily used to treat and prevent infestations with parasites both externally and internally. It has an effect externally to kill parasites such as fleas and mites that live on the skin or in the fur of cats and dogs. In addition it is effective at treating worm parasites that live inside the animal's body.

As combination treatment (for both internal and external infestation) Stronghold flea treatment can help treat:
sarcoptic mange (scabies)
biting lice
ear mites
adult intestinal roundworms
treatment for flea allergy dermatitis (FAD)

Stronghold for dogs can also both treat and prevent:
flea infestations by killing adult fleas, their larvae and their eggs on the animal, and in the litters of pregnant/nursing bitches

Stronghold for dogs can be used to prevent:
heartworm disease

How do I apply Stronghold Spot On?
When you are ready to treat your dog, push the tube through the foil blister pack. Press the cap of the tube down and then open. Part the fur between your dog's shoulder blades so you can see the skin. Then squeeze the contents of the tube onto this area. This liquid is absorbed by the skin and has an effect throughout their body.

Selamectin is the active substance in the anti-parasitic medicine Stronghold Spot On. Selamectin is part of the avermectin class of anit-parasitic medicines. Selamectin works by activating special protiens in the nerve and muscle cells of parasites, which disrupts their normal electrical activity and causes their death or paralysis.
When treating your dog with Stronghold Spot On, please be aware that it is highly flammable. So treatment should be given well away from heat, sparks, open fires or other sources of ignition. You should not smoke, eat or drink while applying as this can lead to accidental transfer to the mouth. You should wash your hands thoroughly once you have treated your dog.

It is advised that you do not handle the treated area until the application has fully absorbed (dried) into the skin. Once empty the tubes should be safely disposed of fully out of sight and reach of all children and pets.

This company never fails to meet expectations. I have two cats on prescription medication and recently one put on a prescription diet, and not only are the prices better than what I'd pay at the vet's office but it gets delivered very quickly. My vet actually referred me to this company and I've used them for over a year now with no issues whatsoever. Brilliant customer service and fast response as well when I have any questions. Highly recommend (and have!).


Would definitely recommend to other pet owners.low pices and prompt delivery.


Easy to buy from, prices are excellent. Saved a fortune as we own 2 big dogs. Will definitely buy from again.


Very poor service, withheld delivery because one of the items was unobtainable.

On 19 Jun 2018 Pet Drugs Online responded:
Thank you for your feedback. I am sorry that you felt our service was poor. We would be pleased to discuss with you further. I have looked into your order which i can see was for one drontal tablet which you ordered at 17.45 pm on the 4th June and we posted this to you on the 5th of June. I cannot see that you ordered any other item or that we delayed sending your order. If you would like to let us know please email

Kind regards
