Stronghold spot-on for Dogs

Affordable Stronghold Flea Treatment and Heartwormer

What Is Stronghold?

Popular among dog parents, Stronghold spot-on is the one stop of treatment of many external and internal parasitic infestations. From eradicating fleas and roundworms in dogs to preventing heartworms and treating sarcoptic mange, ear mites and biting lice the treatment extraordinarily stands out in the performing parameter. The spot-on not only treat adult fleas before they can lay eggs but also kills flea eggs and larvae for an entire month(the ovicidal characteristics lasts only for 3 weeks). Extremely safe for pregnant, breeding and lactating dogs, this monthly treatment even prevents infestation of roundworms from the younger age through litter boxes. It is a waterproof topical solution but only after the 2 hours of its administration.

How Does It Work?

Stronghold treats a wide range of parasites and works on both external and internal parasites. The solution is instantly absorbed by the skin because Selamectin, the active ingredient, has a high affinity for sebaceous glands and skin hence it easily mixes with the skin fluids and blood. It starts killing heartworm larvae in dogs. Selamectin starts destroying fleas, flea larvae, flea eggs, and other parasites.

Selamectin is neurotoxic to parasites. It potentiates glutamate-gated chloride ion channels by increasing the permeability to chloride ions and hyperpolarization of nerve cells in parasites, thus causing the death by paralysis. It also potentiates other chloride channels, including the ones gated by gamma-aminobutyric acid (GABA).

Stronghold remains effective for a full month.
