Seresto Collar for Large Dogs is a flea and tick collar from the brand Elanco designed for dogs over 8 kg. It combines imidacloprid and flumethrin to prevent and treat flea (Ctenocephalides felis) infestations for 7–8 months, and also inhibits flea larva development for up to 10 weeks; plus, it provides effective repellent and acaricidal action against ticks for 8 months, although ticks already present may take more than 48 hours to die after collar application.
It comes in a clinical presentation of 12 units and is administered via topical application. No prescription is needed; please note that it should not be used to treat kittens under 10 weeks of age. It offers a convenient solution for households with large dogs seeking long-lasting protection: you forget about it for months, and your companion can still enjoy walks without as much hassle.
