Advantix for Puppies and Small Dogs Under 4kg (Green) is a monthly spot-on parasite treatment for the smallest dose band in the Advantix range. It's designed for puppies of an appropriate age and adult small-breed dogs weighing under 4 kilograms, and comes as a six-pack for half a year of continuous protection.

Like the rest of the Advantix line, the treatment kills fleas and ticks on contact rather than waiting for a bite, and provides repellent coverage against biting insects such as mosquitoes and sandflies. Lice control is included in the same application. The formula stays in the oily layer of the skin and provides flea cover across the month, with dosing once every four weeks.

For toy breeds and very small dogs, this is the correct weight-banded Advantix option rather than stepping down from a larger dose. Owners choose Advantix over flea-only products when they want the biting-insect coverage, particularly in regions where sandflies and mosquitoes are a year-round issue.
