Advantage Spot-On is a monthly topical flea treatment for large dogs over 25kg. Applied to the back of the neck, it kills adult fleas on contact — they don't need to bite first — and works on larval stages in your dog's environment as well. This 6-pack covers six months of protection and is suitable for adult dogs and puppies.

The active ingredient imidacloprid targets the flea's nervous system, killing adults within an hour and reinfesting fleas within 3–5 minutes of contact. It's water-resistant once dry, so bathing and swimming don't wash it off, and it also treats chewing lice. Because fleas are killed before biting, Advantage helps reduce the itching and irritation associated with flea allergy dermatitis.

Owners choose Advantage for its bite-free action and simple monthly routine — no tablet to disguise, no collar to fit. The topical format suits dogs that spit out oral treatments, and the fast kill time makes it a practical option for households already dealing with an active infestation.
