Vectra 3D For Extra Large Dogs (>88 lbs / >40 kg) – Red
Vectra 3D Red Pack is specifically formulated for extra large dogs weighing >88 lbs (>40 kg). This advanced monthly spot-on treatment combines dinotefuran, pyriproxyfen, and permethrin to provide broad-spectrum protection against fleas, ticks, mosquitoes, sand flies, and biting flies. Its fast-acting contact formula helps repel and kill parasites before they can bite, supporting your dog’s comfort and wellbeing.
Each red-pack applicator contains 8.0 ml of solution, delivering one month of protection with a single application. The triple-action formula kills adult fleas, disrupts the flea lifecycle, and repels a range of external parasites, making it an effective choice for ongoing parasite control. Easy to apply and water resistant, Vectra 3D helps keep extra-large dogs protected with convenient monthly treatment.
