Our in-depth look

Who it's for

Dogs that need routine flea and tick prevention, with owners who prefer a topical treatment.

Who should skip it

Never use dog products on cats. Puppies under 8 weeks, and pregnant, nursing, elderly, sick or medicated dogs should only be treated after talking to your vet, as the FDA guidance on flea and tick products advises.

Tips

Part the fur between the shoulder blades and apply directly to the skin. Keep other pets apart until it dries so they can't lick it. Watch your dog for any reaction after the first dose.
