What Are the Best Brands of Liquid Heartworm Medicines?

Best Brands of Liquid Heartworm Medicines

Heartworm disease is a real headache for us dog parents. Our pets can get it easily, especially in places where mosquitoes are abundant. 

These troublesome bugs serve as carriers of these heartworms and pass them on to dogs when they bite.

These creepy crawlies then invade and grow in the poor pup’s heart, lungs, and blood vessels.

Fortunately, vets know how to fix it!

To protect your pet from the disease, all you need to do is administer medicine regularly to eliminate those young heartworms before they become adults.

And when it comes to these meds, some top choices are:

1. Advantage Multi

Advantage Multi is a liquid heartworm medication that you apply on your pet’s skin usually once a month.

One advantage this medicine has over others is that it also addresses conditions other than heartworms.

It also kills off fleas, hookworms, roundworms, and ear mites.

2. Advocate

Advocate is a go-to liquid medicine that vets really trust.

You only need to apply it once a month and it will keep heartworms, flea tapeworms, and hookworms at bay.

To prevent the development of heartworm larvae, it combines the powers of Moxidectin and Imidacloprid.

The liquid form makes it super simple to administer. 

3. Revolution

Revolution is another topical treatment that you apply to your pet once a month and is distinctive because of its extensive coverage.

This liquid anti-parasite medication also combats fleas, ticks, ear mites, and certain intestinal parasites in addition to heartworms.

Selamectin is present in it, which is commonly used to treat canine sarcoptic mange.

Other brands of heartworm treatment (non-topical, chewables)

  • Heartgard plus
  • Interceptor plus
  • Tri-heart plus
  • Simparica Trio
  • Sentinel Spectrum

What is Moxidectin?

Moxidectin is an active ingredient used in some liquid heartworm medications for dogs. It’s effective against heartworm larvae and other parasites. 

How quickly does Moxidectin work?

Moxidectin gets to work pretty fast. It usually starts protecting your pet against heartworm larvae about a month after you put it on.

How is Moxidectin given?

Giving Moxidectin is easy – you just put the liquid medicine on your pet’s skin.

It soaks in and keeps your furry friend safe from heartworms and other nasty bugs.

This way, your pet stays parasite-free and healthy even if mosquitoes abound in your location.

How is Liquid Heartworm Medicine Being Used?

Using liquid heartworm medicine is pretty straightforward.

First, get a small amount and apply the liquid directly to your pet’s skin. The ideal spots are on the back of their neck or between their shoulder blades. 

The medicine then gets absorbed into their bloodstream.

The active ingredient seeks out the pests and eliminates them, providing a convenient way to ensure your pet’s safety.

How to Choose the Right Liquid Heartworm Medicine?

Picking the right liquid heartworm medicine involves a few key points.

Your first step should be to talk to your pet’s veterinarian to find a medicine that suits your furry pal’s needs. 

The vet has to look into your pet’s size, health concerns, and the types of parasites common in your area. 

For example, if ticks are a problem, your vet might prescribe a medicine that also fights the bloodsuckers. 

What Are the Benefits and Risks of Heartworm Medicines?

The main benefit of giving your pet heartworm medicines is the protection they give from the potentially deadly disease. Some meds also get rid of other pests, so that’s a bonus.

However, like most medications, this liquid protection comes with some drawbacks. Some pets might have mild reactions to it. The most common ones are upset tummies or skin irritation. 

What is Heartworm Disease?

Heartworm disease is a serious health issue that affects dogs. They can get it when they get bitten by mosquitoes carrying heartworm larvae. 

These larvae enter the pet’s bloodstream and travel to the heart, lungs, and blood vessels. As they mature, they start messing up organ function. 

An infection can lead to inflammation, blood vessel blockage, and disruptions in normal blood flow.

What Are the Signs of Heartworm Disease in Dogs?

Heartworm disease can show up as persistent coughing, difficulty breathing, tiredness, and loss of appetite. As this progresses, your pet might start losing weight. 

In severe cases, your poor furry pal might get a swollen belly due to fluid buildup.

How to Prevent Heartworm Disease in Dogs?

Preventing heartworm disease in dogs is all about taking a few smart steps to keep those pesky parasites away. 

  • One key move is giving your furry buddy regular heartworm preventive medication as advised by your vet.
  • Another way is to keep your dog inside during periods when mosquito activity is at its highest and, if necessary, apply insect repellents.
  • I believe that making efforts to lessen the number of mosquitoes in your surroundings is also a smart idea. Get rid of any stagnant water where mosquitoes might breed and multiply.
  • Don’t forget the yearly vet visits! The vet can keep track of your pet’s general health thanks to these check-ups. The vet can run tests to see if your pet is already infected by heartworm. And the sooner you find this out, the better.

Which is the Best Heartworm Medication for My Dog?

Selecting the perfect heartworm medicine hinges on a few things – your pet’s health, age, size, and the parasite that is abundant in your turf. 

Your options lie between chewables, topical treatments, or injectables.

  • Chewables are a hit with pups because they come in flavors that pets like such as chicken or liver.
  • If your dog is a little picky about what they eat, a topical medication may be a better choice. You just need to apply it on parts of your pet’s body that they can’t lick and they’d be protected for the month.
  • Injectable options offer longer protection (usually a year) but might involve some pain.

Frequently Asked Questions (FAQs)

Are there oral liquid heartworm medicines for dogs?

No, there aren’t any liquid heartworm medicines for dogs that can be taken orally. The available options are either topical or injectable. Some dogs aren’t fans of oral meds, making the topical or injectable methods a more hassle-free choice for ensuring their protection against heartworms.

Can I get dog heartworm medicine from compounding pharmacies?

Yes. Compounding pharmacies can create liquid heartworm medicine in special cases. They can personalize it to match your pet’s requirements. This option is particularly useful when you want to address several problems at once or if traditional forms of medication pose challenges.

Can I crush my dog’s heartworm pill and mix it with liquid?

Crushing a heartworm pill is okay if and only if the manufacturer indicates that it is safe to crush. Some medications are designed in a specific way and crushing them could change their effectiveness and taste. If you are unsure, it is best to ask your pet’s vet. 

How often do dogs get heartworms?

Dogs can contract heartworms each time they’re bitten by infected mosquitoes. This means your pet can get infected repeatedly. This is why consistently providing your furry pal with heartworm medication is crucial, especially if you’re in an area where these bothersome bugs are all too common. 

What if I miss giving my dog its heartworm medication?

No worries, it happens. Just let your pet’s vet know. They’ll guide you on the next steps, which often involve giving the missed dose and getting back on track with the regular schedule.

In Conclusion: Liquid Heartworm Medicine for Dogs

Now that you’re familiar with the different options available in the market, you should be in a much better position to make the right choice.

What’s most important to remember is to take pre-emptive actions rather than find solutions later on.
