Heartworm disease in dogs life-threatening and costly to treat. The dog heartworm is a parasitic roundworm that causes dirofilariasis. It spreads between hosts through mosquito bites.

Once they have infested a dog, heartworms reside in the lung arteries and the heart. This causes severe damage to the lung vessels and tissues. Therefore, heartworm infestations result in serious complications for your dog, inevitably leading to death. This is why dog heartworm medicine is so important.

You may be considering heartworm medicine for dogs from the market, online, or directly bought from the vet . It can be difficult to know which to choose. We have compared many different brands and explained their pros and cons for you to decide.

What are Heartworm Medicines?

Heartworm disease is a potentially fatal issue for pets worldwide. Large worms that live inside the heart, lungs, and blood vessels of dogs cause this. This causes severe lung disease and heart failure as well as damage to other internal organs. Unfortunately, our furry friends are natural hosts of heartworms. If untreated, heartworm numbers increase up to several hundred.

There are two types of heartworm medicine for dogs: those that treat heartworm infections, and those that prevent heartworm infections. Preventative medicines come as chewable tablets, topical liquids, pills, and injectable medications. The American Heartworm Society recommends that owners should give their pets year-round dog heartworm medicine.

heartworm tablets for dogs
There are different kinds of heartworn tablets for dogs.

Types of Heartworm Medicine

From pills to capsules, topical to chewable, there is no shortage of options when it comes to taking medication. Surprisingly, there are many differences between the different options that go beyond taste and shelf life. It never hurts to talk to your vet about your options! If your dog refuses tablets and can’t take topical medicines, they should be able to offer alternatives for your pet.

Tablets

Tablets are relatively cheaper to manufacture. This makes them more affordable. In addition, tablets are more stable and typically have a much longer shelf life than other options. Compared to topical treatments, tablets come in variable forms, including quick-release, delayed-release, and extended-release. After taking tablets, dogs are free to swim and bathe as normal.

As with the other treatment options, tablets come with cons too. They are more likely to irritate the intestinal tract, can disintegrate unevenly, and are often less palatable than chewable tablets. Some dogs refuse to take tablets. Defensive and aggressive dogs may not be able to take tablets without sedation.

Topical

Topical treatments are easier to apply in dogs who refuse tablets. Unlike chewable tablets, the ingredients of a topical treatment do not need to be in the bloodstream to start killing parasites. With regular monthly use, some topical treatments reach a steady state. This provides continuous protection from parasites between doses.

On the other hand, topical treatments are more prone to human error. The owner must apply the treatment directly on their pet’s skin, not on the fur, and failing to do so means that the owner could mistakenly believe their pet is protected. In addition, the active ingredients and carriers of the medication often have a bad taste. If your dog licks the product when it is still wet on their fur, it can cause salivation, vomiting, and nausea. Furthermore, some topical medicines require your dog to avoid swimming and bathing after use.

Chewable

The most obvious advantage of chewable tablets is that they are much easier to consume. If your dog has a hard time swallowing standard tablets, or just doesn’t like the taste, chewable tablets are ideal. If they taste good too, your dog is more likely to want to take them instead of viewing them as a negative experience.

In chewable tablets, they often try to hide bad-tasting ingredients with flavorings and sugar. In addition to this, you should take care to ensure that your dog actually chews the tablets. If your dog is likely to swallow the tablet whole, it’s best to break them up into pieces.

10 Best Dog Heartworm Medicines

It’s important to note that some breeds are hypersensitive to some dog heartworm medicines. This is due to a mutation called the MDRI1 mutation. MDRI1 problems most often affect Collies. Many other herding breeds have a genetic predisposition to adverse drug reactions.

The most serious reactions involve antiparasitic agents (ivermectin and milbemycin) and anticancer drugs (vincristine and doxorubicin). Please consult with your vet before treating your pet with potentially dangerous medications.

Dog Heartworm Medicines – FAQ

Need to know anything else about dog heartworm medicine? Feel free to consult our Frequently Asked Questions section for more details. If in doubt, always consult with your vet if you’re concerned about your dog’s health.

Do heartworm medicines need a prescription?

All reputable heartworm medications require a prescription in the USA. It is illegal to obtain an FDA-approved heartworm medication without having a prescription. Your vet will require that your pet has an examination and negative blood test before prescribing your pet with a heartworm preventative. This is because heartworm preventatives will not kill pre-existing heartworms. Once your dog is heartworm-free, your vet will recommend the best medicine for your dog as well as the correct dose. Just be sure to keep your prescription up to date!

At the same time, it is still possible to get heartworm medications without a prescription. Many such products are available online. Some online pharmacies openly flaunt their ability to sell heartworm preventatives without a prescription. These cheaper heartworm medications are typically shipped over from Canada by exploiting cross-border regulatory gaps. The legality of this practice is unclear, and the likelihood that a harmful product might be administered to your pet is obviously increased.

Can heartworm in dogs be cured?

While a heartworm infection is undoubtedly a frightening thing for you and your dog to experience, the good news is that it can be treated! It’s important to be aware that a heartworm infestation cannot be treated at home. Only a vet can administer the correct medication to your pet.

The best drug used to treat heartworm infections is melarsomine dihydrochloride. When administered, this drug kills mature and immature heartworms. The two approved protocols for this drug are the 2-dose and 3-dose. Most veterinarians opt to use the 3-dose treatment as it’s more efficient at killing all of the parasites. Before and after melarsomine treatment, some vets prescribe antibiotics and corticosteroids to reduce inflammation and lung injury associated with dying worms.

As a result of these treatments, some dogs experience coughing, labored breathing, lethargy, and fevers. It’s best to keep your pet in cage confinement to prevent these issues. If properly confined and cared for, most dogs recover from treatment complications within a day. However, all dogs should be confined throughout the course of their treatment and for 4 to 6 weeks after the final melarsomine dose.

How much does heartworm medication cost in the US?

The AAHA suggests that the average cost of preventative heartworm treatment is anywhere from $5 to $15 per month. The cost varies depending on the manufacturer and your individual veterinary practice.

In contrast, the cost of treating heartworm infection costs anywhere from $400 to over $1,000. The cost of your dog’s heartworm treatment depends on the size of your dog and the severity of the infection. Treatment costs include the price of the physical exam, heartworm test, antibiotics, pain relief, melarsomine injections, and any sedation that your dog needs.

How often does a dog need heartworm medication?

Your dog needs heartworm preventative medication once every month. If you miss your pet’s monthly dose by a few days, vets recommend an immediate resumption of treatment. Most monthly heartworm medicines have a safety net of 15 days worth of protection if one dose is missed.

Unlike topical and oral medications that require monthly doses, the heartworm shot is administered twice a year. Proheart 6 is the only FDA-approved shot for heartworm and it offers six months of protection. To ensure that the dosing is as accurate as possible, only vets may administer Proheart 6.
