Heartworm Prevention For Dogs Buyer’s Guide

We all want the best for our furry friends, and the easiest way to ensure they live a long and healthy life is to give them the protection they need from certain diseases. This is where heartworm prevention for dogs becomes so important. Not only is it a potentially deadly disease, but it is easy to protect your dog against it.

To help you find the ideal product, we have created the following buyer’s guide. By the end of it, you’ll be able to make a sensible decision.

What To Look For In Heartworm Prevention For Dog’s

Fast Working

As with any preventative measure, you want it to work as fast as possible. You may have a walk in the nearby fields in mind, a place where the likes of mosquitoes (which can potentially house heartworm) may be. Most products tend to work within 12 hours and anything much longer than this is unnecessary.

Multi-Purpose

The formula for most reputable brands will include prevention for other nasties such as fleas and ticks. This can help put an owner’s mind at rest, but also save money on multiple treatments. Heartworm prevention for dogs should be able to kill fleas and ticks on impact and get rid of any existing eggs as well. Again, you will want this to be fast-acting and long-lasting. Which brings us to…

Long-Lasting

No one wants to have to spray their dog every day to ensure they are protected, thankfully, this is something that most brands avoid. One application usually lasts a few months, or at least one. To help make it easier to remember, mark the next treatment on the calendar so you can ensure your pooch is always protected. 

Easy Application

Most products will be either a chewable tablet that can go inside a treat or among their meal or via a tube that drops a liquid, usually onto the back of the neck. A spray or other method can be distressing for a dog. 

The Right Strength

This is worth paying attention to since aq formula designed for a small dog will not be strong enough for a large breed. On the other side of this, using a formula that is too strong for a small breed is not a good idea. This is why most brands make their products with different dogs in mind. This ensures that houses with dogs of different breeds can use brands and products they trust.

What Is A Heartworm?

Spread from mosquito to a dog upon a bite, this is a type of roundworm that is a parasite and can lead to expensive vet bills and could even be fatal. It is the female heartworms that produce offspring inside a dog that make their way into the bloodstream. This can result in some nasty side effects, which we will go into now.

What Are The Symptoms?

The symptoms depend on the number of worms that are living inside the dog. If they have had months to multiply, then expect the symptoms to be worse. It may not be obvious straight away and some of the symptoms of the early stages can include an occasional cough which may not usually be cause for concern on its own.

One of the most common symptoms is tiredness, especially if it is persistent, as is any sign of difficulty when breathing. Also, heart failure, a lack of energy are common. Since heartworm can cause lung disease and failure, it is important to consult a vet if you suspect your dog has any of the above. 

Can A Dog Transmit Heartworm To Another Dog?

No, it cannot. Heartworm can only be transmitted via a mosquito bite so one dog being close to another is not enough for it to transmit heartworm disease. 

Can Cats Get Heartworm Disease?

If you have other household pets including cats, ferrets, there is a chance that they too can contract heartworm disease, but not from your dog. The worms do not tend to survive as well inside a cat’s body as they do in a dog which is why cases are less common.

Is There A Treatment For Heartworm Disease?

For dogs, there are certain treatments available that are approved by the FDA. These are capable of treating infections that tend to work better the earlier heartworm has been diagnosed. This can be via injection or other methods such as a topical solution but the strength and type of treatment will vary depending on the severity and should be recommended by a vet.

Treatment may start with a series of blood tests, as well as X-rays to examine the severity. This is why prevention is the best form of ensuring your dog is protected. A simple and cheap alternative to what can be a painful time for a dog is heartworm prevention for dogs. 

What Is The Best Heartworm Prevention For Dogs?

Having considered the reputable products available, we found VECTRA 3D 6 Pack Blue Dogs to be best. It is available in different strengths for most dog breeds and is fine to use when over 8 weeks old. The 6 months supply is easy to apply and dries quickly. Not that this matter too much as it is also waterproof so there is no risk of it being washed off. 

Because it also kills fleas, ticks, and mites among other nasties, it is a bit of an all in one formula. Each application lasts a month and it is also a good value compared to a lot of the competition. 

How Long Does Heartworm Prevention For Dogs Last?

This varies depending on the product, but most tend to last around a month before you need to re-apply. The easiest way to do this is to set a reminder on your phone, apply on the first of every month, or write it on the calendar.
