## 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. After application, the treatment rapidly covers your dog's entire body and deposits in the sebaceous glands. These glands act as a reservoir, continuously replenishing the treatment onto your dog, working even if your dog gets wet (2). Apply monthly to ensure your dog is protected all year long. So, no matter your plans, FRONTLINE Shield protects from fleas and ticks —inside your house, outside on walks and hikes, and everywhere in-between.

Review: Set a monthly reminder on your phone! - Great results without the neurological side effects of oral medications. It would be rare for us to find a tick on our farm dogs. No fleas either!
Review: Works without worry of the other toxic treatments - We try to keep our chemical load on our dogs low but with ticks becoming worse, we had to resort to something not natural. This is the least harmful but effective one and it was 100% effective with 2 applications before the cold weather hit. Hopefully we don't need it and we can get ahead of the ticks with DE in the yard, but all 6 dogs had no adverse affects.

### ⭐⭐⭐⭐⭐ Kills ticks once they bite
*by E***S on October 31, 2023*

I found a tick on my dog while petting him. The tick fell onto the floor, dead, with the head attached! The tick had bitten my dog because there was a small welt but the medicine killed it! My dog is mixed breed, 50 pounds.
