Dog Flea Drops and Spot Ons

Flea drops are topical flea treatments for dogs and cats that are applied in a single spot directly on the skin where your pet can't reach to lick the medication off, generally the neck and shoulder area. Flea drops or spot-ons for dogs protect your pet from biting pests and the diseases they spread. Easy to apply and long lasting, spot-on treatments are an effective form of flea and tick control. We carry convenient multipacks of topical flea medications, so you can buy the amount you need based on your climate and other environmental factors that affect outbreaks of fleas. With top brands like FRONTLINE®, Advantage®, K9 Advantix®, SENTRY® and more, PetSmart is your source for reliable, safe, flea and tick drops and topical treatments for dogs.
