What is Vectra 3D for Dogs?

Vectra 3D for Dogs is an easy-to-administer broad-spectrum ectoparasiticide. It is developed to protect your furry friends from common external parasites, including fleas, ticks, flies and mosquitoes. This topical flea treatment kills and repels parasites on contact before they can bite. It is effective against adult fleas, as well as flea eggs and larvae, reducing the risk of future infestations.

Vectra 3D Spot-on for Dogs begins reducing flea feeding in minutes while killing them within hours. It helps repel ticks (brown dog ticks) and reduces the risk of attachment through its repellent ("hot foot") effect. This flea and tick treatment provides persistent repellent activity, which helps prevent bites from flies and mosquitoes, thereby reducing the risk of Leishmaniasis. Vectra 3D comes in a patented applicator with an elongated smooth ball tip for easy dosing. It is a quick-drying, non-greasy and water-resistant formula that stays effective even after swimming and bathing.
