Advantage Blue is a monthly spot-on flea treatment for extra large dogs weighing 25 kg and above. Applied to the back of the neck, it starts killing fleas within 20 minutes of application and maintains protection throughout the month. This pack contains 6 pipettes — enough for six months of continuous coverage.

The active ingredient, imidacloprid, disrupts the nervous system of fleas on contact, killing adult fleas before they can bite or lay eggs. It also eliminates flea larvae in the dog's immediate environment, helping break the flea life cycle at the source. Advantage is additionally effective against chewing lice, clearing them within 7 days of application. The formula is water-resistant once dry, so regular bathing doesn't compromise monthly protection.

Advantage suits owners who want a dedicated flea-only treatment with a fast kill time. It doesn't cover ticks or heartworm, making it a practical choice to pair with a separate wormer, and its water-resistant formula holds up through outdoor activity and bathing.
