FRONTLINE Shield Flea & Tick Treatment for X-Large Dogs (81–120 lbs) — 3-Count

Fast, long-lasting protection for big dogs

FRONTLINE Shield for Dogs is the fastest working option from the leading flea and tick protection brand. This 3‑in‑1 topical treatment targets fleas, ticks, and lice, while offering repellency against ticks and mosquitoes. The product is designed to cover your dog quickly and continue to replenish protection over time, helping you keep up with a busy outdoor lifestyle.

Ideal for large breeds, including X‑Large dogs weighing 81–120 lbs, it also fits households with puppies as young as 9 weeks and at least 5 pounds. After application, the formula spreads across the skin and deposits in sebaceous glands, creating a reservoir that can help maintain protection even if your dog gets wet. Monthly reapplication helps sustain year‑round coverage, whether you’re at home, on walks, or exploring outdoors.

What makes FRONTLINE Shield stand out

• Repels ticks and mosquitoes, adding a layer of protection during outdoor activities.
