Seresto Anti-parasitic collar for large dogs

Seresto Anti-Parasitic Collar for Large Dogs is a veterinary medicinal collar, specially designed to prevent and treat ectoparasite infestations in dogs weighing over 8 kg. This innovative treatment works by gradually releasing active ingredients into the skin’s lipid layer, providing long-lasting protection against parasite-borne diseases.

Polymer matrix and continuous active release

The collar’s action relies on an advanced polymer matrix that ensures the steady diffusion of two key active ingredients—imidaclopride and flumethrin—for a documented period of up to 8 months. Imidaclopride targets fleas and lice by overwhelming their synaptic receptors, while flumethrin delivers acaricidal and repellent effects (anti-feeding action) against ticks. By reducing parasite contact with the host, this collar helps lower the risk of vector-borne disease transmission. Additionally, it helps neutralise flea larvae in the animal’s immediate surroundings, breaking the reinfestation cycle.

Physicochemical properties and safety mechanisms

Measuring 70 cm in length and featuring a grey design, the Seresto collar is completely odourless and water-resistant, ensuring the treatment remains effective even after exposure to moisture. For added safety, the collar includes a two-stage protection system: a pre-defined breakaway point and an adjustable loop mechanism, allowing the animal to free itself if the collar becomes snagged. Developed by Elanco, this preventive veterinary solution is engineered to maintain consistent parasitic control, offering stable long-term protection.
