## 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.

Review: Effective and fast delivery - Recommending this product, very effective and fast delivery
Review: Worth it!! - Love this! No more bites, keeps all the bugs off my dog, no side effects found, no hair loss , bit pricey but worth it, cut open in a rounded shape so you don’t scratch dog when applying, cut, squeeze and done. Wrote date on box. Will continue to buy for start of spring to first snow. I put on back between shoulder blades and on top between hips just above tail so he can lick at it. Easy to squeeze and use
