Heartworm Prevention For Dogs Guide

There are certain things we can protect our pets from and heartworm is one of the most serious diseases to avoid. Potentially fatal and transferred through the bite of a Mosquito, your pooch can benefit from a quality heartworm protection for dogs. Most products are designed to rid your furry friend of fleas and ticks yet double up as a mozzie repellent. 

Still, not all products are as effective as you might like which is why we have created the following buyer’s guide. At the end of it, you’ll know everything you need to so you can make a sensible purchase and protect your dog.

What To Look For In Heartworm Prevention For Dogs 

Easy Administration

Being able to apply the heartworm prevention for dogs is part of the battle for some people. A nervous pet might be reluctant to sit still if you use a spray which is why the tab form or a collar is a good option. These tend to last longer as well as a spray needs to be reapplied every 2-3 days in most cases.

Universal Protection

Not only will your heartworm prevention for dogs protect against mosquito bites, but many of them are great for getting rid of lice, fleas, ticks, biting flies, and more. This makes it easy for you to protect against some of the potentially dangerous infections, as well as the irritating bites of the likes of ticks.

The Active Ingredient(s)

Although the active ingredients differ from product to product, you should check to see how likely side effects are before using it. Most side effects are rare but it is always a good idea to do a little research before you apply it.

Waterproof Protection

Because most heartworm prevention for dogs lasts around a month, the product you choose needs to be waterproof. There is no predicting what your dog will get up to over the course of the next 30 days and you should not have to neglect their regular bathtime. The best products are those that stay active to protect your dog, even after a splash around.

How Long It Lasts

Some products only last a couple of days – these are usually the spray type heartworm prevention, but the best products are those that give ongoing protection. Around 30 days should be the minimum amount of protection which is less stressful on your dog and something you don’t have to remember to do every day.

Fast working Protection

Some products take a little longer to protect your dog from heartworm disease, most notably the collar types that take a day or two. The spot application products tend to work within a matter of hours which means you can let your dog outside with the confidence that they are protected.

What Are Heartworms?

Heartworm is a parasite that can be transferred via a mosquito bite which is why heartworm prevention tends to be in the form of a mosquito repellent. It spreads through the body via the lungs or heart, attacking vital organs along the way.

It is more common in dogs although cats and ferrets are two of the other common victims of heartworm disease.

How Much Does Heartworm Prevention For Dogs Cost?

Depending on what product you purchase, heartworm prevention doesn’t have to cost a lot. Most applications tend to last around a month and are bought in packs of 3 or 6. This means for around $25 – $50 you can protect your dog from this disease (and other nasties) for months before you need to consider repurchasing.

What Are The Possible Side Effects Of Using Heartworm Prevention?

Although all heartworm prevention for dogs is safe to use, it is not uncommon for some to suffer from side effects as a result of the application. Because your dog may not have been exposed to some of the active ingredients before, such a reaction might be unexpected.

It is always a good idea to keep an eye on your dog after applying the heartworm prevention and lookout for some of the common signs of side effects such as the following:

  • Diarrhea
  • Excessive drooling
  • Weakness
  • Lethargy
  • Loss of appetite
  • Irritable behavior
  • Dehydration
  • Vomiting
  • Temporary blindness

Because these side effects can be upsetting to see and some are more serious than others, it is always a good idea to consult your vet before you administer the heartworm prevention.

How To Choose The Right Heartworm Prevention For Dogs

Most products come in different strengths which make them appropriate for different breeds. The size and weight of your dog need to be considered before you buy heartworm prevention. 

If you buy the wrong strength you risk buying a product that is ineffective for a larger dog, or potentially dangerous for smaller breeds. 

How Many Dogs Get Heartworm Disease Every Year?

Approximately 250,000 dogs get heartworm disease every year. On a global scale, this still sounds like a lot which is why so many people opt for the best heartworm prevention for dogs. 

Can Garlic Prevent Heartworm In Dogs?

Home remedies can be effective but be wary of giving your dog garlic to prevent heartworm. For a start, it is not as effective as the prevention remedies we have recommended but also, excessive amounts of garlic can be toxic to a dog.

Does Heartworm Go Away On Its Own?

Once it has been injected via the mosquitoes bite, a heartworm can grow up to 10 inches long in your dog. They do not leave your dog via their stools, nor do they dissolve and they can live in a dog’s heart for several years. 

This is why it is important to use quality heartworm prevention for dogs so your dog doesn’t have to suffer the discomfort. The side effects that come as a result of medicine used to rid your dog of heartworm can cause side effects and can cause your furry friend some pain.
