Advantage Multi for dogs controls and eliminates parasites that prey on dogs, such as fleas, heartworms, and other internal parasitic worms. Available with a prescription from your veterinarian, Advantage Multi is the latest formulation in the Advantage family of anti-parasite medications. Its precursors are Advantage I and Advantage II, which are effective against fleas and ticks.
A typical price for Advantage Multi for dogs is $113.15 for 6 months of the topical medication. This is the only form available, although it may be dispensed in 3-month sizes as well. The cost for a 3-month package is $58.65.
Dosage of this medication is based on the dog’s weight. Advantage Multi is administered in the following doses:
- 3–9 pounds: 0.4 milliliter
- 9.1–20 pounds: 1.0 milliliter
- 20.1–55 pounds: 2.5 milliliters
- 55.1–88 pounds: 4.0 milliliters
- 88.1–110 pounds: 5.0 milliliters
Peel the cover off the medication applicator and snap off the top.
Have the dog in a standing position.
Part the hair at a spot between the shoulder blades.
Drop the contents onto the exposed skin.
If using Multi on a large dog, break the dose into 3 or 4 spots around the shoulders and neck or down the back where the dog can’t lick them.
Observe the dog for 30 minutes to ensure they aren’t licking the dosage site(s).
Be sure to protect clothing from being contaminated by the medication. If this happens accidentally, remove the clothing at once and wash it. Protect hands with gloves, if available. Wash hands thoroughly after handling Multi.
Advantage Multi for dogs has been shown to be effective against adult fleas, and worms such as pinworms, whipworms, and roundworms. It prevents ear mites as well. It's also effective against heartworm microfilaria and adult heartworms, as demonstrated in a study published in Parasites and Vectors.
This ability to prevent and potentially cure heartworm infestations is a distinguishing feature of Advantage Multi for dogs. Its ingredients include 2.5 % moxidectin, along with 10% imidacloprid.
There are many possible side effects in dogs taking Advantage Multi. Some will resolve on their own about ten days after administration. They include:

- Dilated pupils
- Muscle tremors
Advantage Multi for dogs should also not be used on sick, debilitated, or underweight dogs, or puppies less than 7 weeks old and under 3 pounds.
Advantage Multi for dogs is prescribed as an off-label drug. Some prescription medications that may not be fully vetted for use in canines may, in the veterinarian’s opinion, be effective for certain illnesses or as preventive medicine. If the vet instructs you to give the medication in a way that’s different from label directions, follow the veterinarian’s instructions.
