Frontline Plus for Medium Dogs is a monthly spot-on flea and tick treatment for dogs weighing 10 to 20kg — the blue-pack variant in the Frontline Plus range. This six-pipette pack covers six months, which lines up with the standard treatment cycle recommended for year-round parasite control in most parts of Australia.

Unlike the basic Frontline spot-on, the Plus formulation adds an insect growth regulator that kills flea eggs and larvae in the dog's environment, not just the adult fleas on the animal. That matters if you've had a flea outbreak indoors — breaking the life cycle prevents re-infestation from carpets, bedding and floorboards. It also controls brown dog ticks and paralysis ticks when applied at the correct interval.

The spot-on format suits dogs that won't tolerate chews or sprays, and applies quickly along the back between the shoulder blades. Owners buying the six-pack are typically committing to year-round coverage rather than seasonal treatment, which is the sensible approach in tick-prone regions.
