Advocate Spot On contains two active substances, imidacloprid and moxidectin.

Advocate comes in different strengths and pack sizes, depending on the size of the animal being treated. The medicine can only be obtained with a prescription. Advocate is applied from pre-filled pipettes. These are small plastic droppers, available in different sizes depending on the size of the animal, which are filled with the correct amount of Advocate for one treatment. The content of a full pipette is applied onto the animal’s skin, after parting the fur. Advocate for dogs is applied between the shoulder blades at the bottom of the dog’s head, but for large dogs (above 25 kg) the product should be applied in 3 or 4 spots along the dog’s back, whilst it is standing, from between its shoulder blades to the base of its tail.

The dose and frequency of application depends on why Advocate is being used; the package leaflet includes detailed information on dosage and duration of treatment.

Advocate Spot On is available to buy from Pet Drugs Online at up to 52% cheaper than your vet.

How does Advocate Spot On work?

Imidacloprid interferes with certain specific receptors (nicotinergic acetylcholine receptors) in the nervous systems of lice and fleas, which results in their subsequent paralysis and death.

Moxidectin causes paralysis and death of nematodes and heartworms by interfering with the way signals are passed between nerve cells (neurotransmission) in the parasites’ nervous system.
