## Description

FRONTLINE Shield for Dogs, from the number 1 name in flea and tick protection (1), is the fastest working FRONTLINE product. It is proven flea and tick protection with repellency action against ticks and mosquitoes. FRONTLINE Shield repels ticks that may transmit Lyme disease and mosquitos that may lead to heartworm disease.

It is an effective flea and tick treatment for pups big and small, effective for puppies as young as 9 weeks and weighing at least 5 pounds.

Review: A dog saver! - My boy is a tick and mosquito magnet. Mosquitoes especially would swarm him and his head in particular, with this product they ignore him now. Ticks are fewer now as well. He has shown no GI issues, which is huge because he’s a GSD and super sensitive. Hiking is so much more enjoyable.
Review: Tick Flea protection on dog - Excellent flea & tick prevention. But use disposable gloves. The package is a bit difficult to open, requiring scissors for outer shell, inner shell and liquid container. I smooth the Frontline liquid all the way down the top of the back. With disposal gloves, I smooth the liquid into her spine from withers to end of spine, not on tail. I've used this product for 20 years with successful prevention
