How K9 Advantix II for Dogs work?

When Advantage is applied to your pet, it spreads on the surface of the skin at the hair root level, aided by body movement, to provide whole body coverage. The revolutionary chemistry causes the flea's nervous system to become impaired, and the flea dies.
Reinfesting fleas, which likely come from the pet's environment or outdoors, will be killed within two hours, with protection against further flea infestation for up to a month.

Helpful Tips:

Treated dogs should not be handled especially by children until the application site is dry. This may be ensured by treating the dogs e.g. in the evening. In this case, recently treated dogs should not be allowed to sleep together with their owner, especially children.

Advantix® is easy to apply – one dose, once or twice a month, simply applied onto the skin of the animals and available in four different pipette sizes. A small dog below 4 kg weight requires no more than a single spot on its neck with the advantix® 0.4 ml pipette. For a big dog of more than 25 kg weight the advantix® 4.0 ml pipette should be applied on four spots along its back.

With monthly treatment the pet gains year-round protection against nasty parasites. For dermal use only.

The dog should be standing for easy application. The entire contents of the advantix® pipette should be applied evenly to four spots on the top of the back from the shoulder to the base of the tail. At each spot, part the hair until the skin is visible. Place the tip of the pipette on the skin and gently squeeze to expel a portion of the solution on the skin. Do not apply an excessive amount of solution at any one spot that could cause some of the solution to run off the side of the dog.

Indications for use

Advantix® Spot on is designed for dermal application. Dogs with body weights under 10 kg should be treated at a single spot. The recommended minimum dose is: 10 mg/kg body weight (bw) Imidacloprid and 50 mg/kg body weight (bw) Permethrin.
