Overview

FRONTLINE Shield for Medium Dogs offers a trusted approach to flea and tick protection, backed by the brand’s long‑standing protection heritage. This 3‑in‑1 topical treatment combines fast action with ongoing coverage for a full 30 days, and it remains effective even if your dog gets wet. It’s designed for dogs weighing 21 to 40 pounds, including puppies as young as 9 weeks that meet the minimum weight.

What makes FRONTLINE Shield stand out

• Proven flea and tick protection with repellency against ticks and mosquitoes, helping reduce exposure on daily adventures.
• Kills and helps deter all life stages of ticks, including those that may transmit Lyme disease, when used as directed.
• Kills chewing lice and adult fleas, as well as fleas at the egg and larva stages, to help slow re‑infestation in your home.
• Easy to apply and waterproof for up to 24 hours, offering continuous coverage for a full 30 days.
• Suitable for a wide range of dogs, from puppies at 9 weeks of age and weighing at least 5 pounds to larger breeds within the target weight range.

How it fits into real life

After you apply FRONTLINE Shield, the treatment quickly makes its way across the body and deposits in the sebaceous glands. These glands act as a reservoir, providing ongoing protection that can endure typical outdoor activities, rainy days, and even a spa day at the park. You may notice your dog remains more comfortable during walks and playtime, with less concern about fleas or ticks invading companionship moments.
