Seresto Flea, Tick & Worming5 products

Seresto makes long-acting flea and tick collars for dogs, designed to release active ingredients steadily over an eight-month window rather than relying on monthly top-ups. The dog range splits across two weight tiers, with collars for dogs and puppies under 8kg and medium-to-large collars for dogs over 8kg. It's a fit for owners who'd rather a fit-and-forget parasite solution than remember a monthly chew or spot-on.
