Frontline for Dogs is a spot on treatment for fleas and ticks and is applied directly to the skin of the animal at the back of the neck.

Applied once a month will provide continuous protection against fleas and ticks.

This Frontline for Dogs Spot On treatment is especially for large dogs weighing between 20-40kg, making this the ideal spot on flea treatment for Labradors, Greyounds, Dobermans, Retrievers, German Shepherds, Afghan Hounds, Setters and larger Spaniels.

In addition to using Frontline Spot On, a household spray may be required to combat fleas which may be dormant or may not have hatched within the household.
