Advecta Ultra for Extra Large Dogs – Flea & Tick Prevention, Waterproof Topical Drops (6‑Month Supply)

Overview

Advecta Ultra is a waterproof topical protection designed for extra large dogs (over 55 lbs). It uses the same active ingredients as K9 Advantix II—imidacloprid, permethrin, and pyriproxyfen—to both kill fleas and repel ticks and mosquitoes. This fast acting formula works through contact, so bites can be prevented even if your dog does not chew or scratch. It also targets the flea life cycle by affecting eggs and larvae, helping to reduce reinfestation over time. Many owners choose this topical option as an alternative to oral pills, and you can use it alongside a flea comb during grooming to maximize protection. The fragrance free formula aims to minimize scent on your pet, and the product remains effective if the coat gets wet after the initial 24 hours. Protection lasts up to 30 days when applied as directed.
