Overview

FRONTLINE Shield for Large Dogs targets fleas and ticks while offering repellency against ticks and mosquitoes. Marketed as one of FRONTLINE’s fastest-acting options, this 3-in-1 topical aims to deliver coverage for a full 30 days per application. It’s designed for dogs in the 41–80 lb range, including puppies as young as 9 weeks and at least 5 pounds, making it a versatile choice for households with mixed ages and sizes.

Why this matters for you and your dog

In real life, flea and tick protection often needs to work quickly and stay effective through daily activities. This treatment is formulated to rapidly spread across your dog’s body and deposit in sebaceous glands, creating a reservoir that replenishes protection over time. The product also provides repellency against ticks that may carry Lyme disease and mosquitoes that could pose heartworm risk, helping you plan outdoor adventures with more confidence.

  • Repels ticks that may transmit Lyme disease and mosquitoes that may lead to heartworm risk.
  • Kills fleas and ticks across life stages, with a focus on reducing re-infestations.
  • Waterproof formula that remains active after moisture exposure, helping protection endure play and weather.

How to use and what to expect

Apply monthly to ensure year-round protection. After application, the treatment quickly coats the skin and hair, then relies on sebaceous glands to maintain a steady release. With regular monthly use, many pet households find it fits neatly into routine care, whether you’re at home, on walks, or exploring new trails.

  • Lasts for a full 30 days per application and can be part of a year-round routine.
  • Effective for dogs of varying sizes, including large breeds and younger puppies (9 weeks+, 5 lb minimum).
  • Waterproof 24 hours after application, helping maintain protection through common outdoor activities.

Subscribing and saving can simplify ongoing protection, ensuring you don’t miss a dose. For more updates on FRONTLINE products, features, tips, and offerings, visit the brand store and follow the line of products.
