NexGard for Large Dogs is a monthly flea and tick chew for dogs weighing 25.1 to 50kg. Each beef-flavoured chew delivers a full month of protection against fleas, paralysis ticks, brown dog ticks, mites and biting lice — administered as a treat rather than a spot-on or collar.

The active ingredient afoxolaner kills fleas before they can lay eggs, breaking the household infestation cycle, and provides critical protection against the Australian paralysis tick. The chew format sidesteps the usual problems with spot-on treatments — no waiting to dry, no risk of it washing off in the pool or bath, and no residue on the coat that children or other pets can contact.

Owners choose NexGard when they want tick and flea cover that's easy to give and hard to forget. Dogs generally take the beef-flavoured chew as a treat, which removes the wrestle that comes with topical applications, and the monthly rhythm is straightforward to track.
