Vectra 3D for Medium dogs is formulated to provide broad-spectrum monthly protection for dogs >22-55 lbs (10–25 kg). Presented in a blue pack with a 3.6 ml pipette, this advanced spot-on treatment helps repel and kill fleas, ticks, mosquitoes, sand flies, and biting flies before they can bite.
Its triple-action formula works through contact to target parasites at multiple life stages, helping reduce infestations and minimise the risk of vector-borne diseases. The easy line-on application ensures smooth distribution across your dog’s skin and coat for consistent protection throughout the month.
Vectra 3D works through a synergistic combination of active ingredients that target parasites on contact. Dinotefuran rapidly kills adult fleas, pyriproxyfen interrupts the flea lifecycle by preventing immature fleas from developing, and permethrin repels and kills ticks, mosquitoes, sand flies, and biting flies. Its repellent and anti-feeding effects help prevent parasites from attaching and biting, reducing the risk of disease transmission while helping keep your dog protected for a full month.
Your veterinarian can help determine the appropriate pack for your dog’s weight and lifestyle.
