Frontline Plus for Extra Large Dogs 40-60kg (Red) is a monthly spot-on flea and tick treatment for the largest dose band in the Frontline Plus range. The 6-pipette pack is a six-month supply for one dog in the 40 to 60 kilogram weight range, and the red colour coding matches the extra-large dose size.

Frontline Plus kills adult fleas and also targets flea eggs and larvae in the dog's surrounding environment, breaking the life cycle rather than only treating what's currently on the dog. It also controls brown dog ticks, paralysis ticks and biting lice. Once applied to the back of the neck, it's fast-acting and kills fleas and their larvae within 24 to 48 hours, with a month of ongoing cover against re-infestation.

Frontline Plus is one of the longest-running monthly flea and tick products in Australia and is a regular starting point for owners of very large breeds. The Red 40-60kg dose covers the weights typical of Great Danes, Saint Bernards, Mastiffs and similarly sized dogs, and is the right dose rather than combining smaller doses.
