Frontline Plus Blue for Medium Dogs 10–20kg is a monthly spot-on flea and tick treatment in a convenient 3-pack. It protects against fleas (adults, eggs, and larvae), paralysis ticks, brown dog ticks, and biting lice — suited to the standard medium-breed weight band.

Each pipette delivers fipronil and S-methoprene: fipronil kills adult fleas and ticks on contact, while S-methoprene prevents immature flea stages from maturing in the dog's environment. Monthly application to the back of the neck provides protection against paralysis ticks (reapply every 2 weeks in heavy tick areas) and controls brown dog ticks for a full month. Water-resistant after 24 hours.

Frontline Plus earns its place as a go-to for households where tick exposure is a real concern alongside fleas. The environmental flea life-cycle control is what sets it apart from flea-only products, and the monthly routine keeps dosing simple across the warmer months.
