Parasites like fleas and worms are dangerous creatures that can put your furry companion’s health at risk. Therefore, it is crucial to follow a preventive care routine using a vet-recommended parasite treatment. Among the plethora of options available today, pet parents are often confused between choosing between two popular treatments on the market, i.e., Advantage Multi and Heartgard Plus.
This blog compares both treatments and arms you with information you need to make an informed decision for your dog.
Advantage Multi is a broad-spectrum, topical treatment for puppies from 7 weeks of age and at least 3 lbs of body weight. It provides protection against fleas, roundworms, hookworms, whipworms, sarcoptic mange and heartworm disease for one month.
Heartgard Plus is a highly palatable, beef-flavored oral treatment for puppies and dogs 6 weeks of age and older. It helps prevent heartworm disease and treats and controls intestinal worms like roundworms and hookworms.
Before we get into the key differences between Advantage Multi and Heartgard Plus, let’s go through the traits shared by these products:
The following points differentiate Advantage Multi and Heartgard Plus for dogs:
Advantage Multi is a ready-to-use topical solution that is applied directly to the skin, whereas Heartgard Plus is available as a chewable tablet that is administered orally.
Advantage Multi contains Imidacloprid and Moxidectin as active ingredients, and Heartgard Plus is formulated with Ivermectin and Pyrantel Pamoate.
Advantage Multi is recommended for puppies and dogs from 7 weeks of age, whereas Heartgard Plus is suitable for puppies and dogs from 6 weeks of age.
Both treatments are labeled for heartworm disease prevention and the treatment and control of hookworms and roundworms. But Advantage Multi offers additional protection against:
One of the major differences between these treatments is that Advantage Multi for Dogs is also labelled for the treatment of circulating heartworm microfilariae in heartworm-positive dogs.
However, it is important to note that heartworm-positive dogs must be treated as per veterinary recommendations only. Neither of these treatments is effective against adult heartworms.
Advantage Multi is a topical treatment, so the label contains specific bathing instructions.
Shampooing 90 minutes after treatment does not reduce its heartworm-prevention effectiveness, and shampooing or water immersion 4 days after treatment does not reduce effectiveness against fleas. However, an encounter with water before this duration may hamper the efficacy.
On the other hand, Heartgard Plus is an oral treatment, so bathing or water exposure does not affect efficacy of the treatment.
The below table provides a side-by-side comparison of Heartgard Plus and Advantage Multi

All in all, both Advantage Multi and Heartgard Plus are good choices for heartworm disease prevention and hookworm and roundworm treatment and control. But if you are looking for additional protection from fleas, whipworms, and sarcoptic mange, then Advantage Multi may be an appropriate choice for your dog.
Other important factors in choosing between these treatments are their mode of administration and suitability. If your dog is fussy and is 7 weeks of age or above, then you can ask your vet about the appropriateness of Advantage Multi for your dog, as it comes in a topical form. On the other hand, if your furball is only 6 weeks of age and is fond of palatable chewables, then Heartgard Plus may be a good option.
If you want to pick Heartgard Plus for protection against major types of worms in dogs, your vet may recommend a separate treatment for parasites like fleas, ticks, and mange if required.
In the end, your dog’s parasite exposure risk can largely affect your decision in choosing between Advantage Multi and Heartgard Plus. Make sure you consult the vet for expert recommendations before starting any parasite treatment for your dog.
