Heartworm in Dogs: Our Experience, Our Holistic Approach, and What Every Owner Should Understand

At Vom Geliebten Haus, we have always tried to be transparent about the realities of dog ownership, breeding, importing, and long-term canine health. Sometimes those conversations are easy and joyful. Other times, they involve difficult experiences that shape the way we approach prevention, wellness, and responsibility moving forward.

For many years, we quietly carried one of those experiences privately.

Today, we feel it is important to share it — not to create fear, but to provide education, perspective, and honest reflection for dog owners who may someday face similar situations.

Yes — One of Our Imported Dogs Arrived Heartworm Positive

Many years ago, we imported a female German Shepherd into our breeding program. She was intended to become a future breeding prospect and was a dog we were very excited about.

As part of our standard veterinary evaluation after arrival to the United States, we performed comprehensive testing and bloodwork, including a 4DX test.

That is when we discovered she was heartworm positive.

To say we were devastated would be an understatement.

At the time, we operated in a kennel environment with multiple dogs, shared outdoor areas, and naturally — mosquitoes. And that is where the fear truly began.

Heartworm disease is transmitted through mosquitoes. It does not spread directly dog-to-dog through casual contact, bowls, crates, or saliva. However, if a mosquito bites an infected dog carrying microfilariae and then bites another dog, transmission can occur.

That reality was terrifying for us.

Because despite every effort, fully quarantining a dog from mosquito exposure in a real-world kennel setting was essentially impossible. Even if dogs were separated indoors or rotated outside at different times, mosquitoes do not respect schedules, fencing, or management plans.

There was always potential risk.

And that experience changed the way we viewed prevention forever.

The Important Truth About Heartworm Risk

One thing we strongly believe owners deserve to hear honestly is this:

The chances of heartworm infection may be low in some regions — but they are never zero.

We hear many people say:

• “We live up north.”

• “Mosquito season is short.”

• “My dog is indoors.”

• “Heartworm isn’t common here.”

And while risk levels absolutely vary by region and climate, mosquitoes exist almost everywhere. Dogs travel. Rescue dogs are transported across states. Imported dogs enter the country. Climate patterns change. Warm seasons fluctuate.

All it takes is one infected mosquito.

The overall odds may be low for some dogs.

But low does not mean impossible.

And unfortunately, we learned that firsthand.

Our Dog’s Treatment Journey

Once the diagnosis was confirmed, we moved immediately into treatment planning with our veterinarian.

We chose the standard three-injection heartworm treatment protocol using melarsomine injections. The process was emotionally exhausting, physically demanding on the dog, and financially significant.

At the time, treatment cost us approximately $1,500 — and that was many years ago. Today, costs can be substantially higher depending on location, complications, diagnostics, hospitalization, medications, and follow-up care.

Heartworm treatment is not simple.

It is not “just a shot.”

It is a serious medical process that places stress on the body and especially on the cardiovascular and pulmonary systems.

One of the hardest aspects of treatment is strict activity restriction. When heartworms die, fragments can lodge in the lungs and blood vessels. Excessive exercise during treatment can increase risks of complications.

Thankfully, our dog responded well.

She survived treatment successfully and is still alive today, living a happy and loved life.

But that experience permanently influenced our decisions moving forward.

Why We Chose Not to Breed Her

Although she was originally intended as a breeding prospect, we made the decision after treatment to spay her and place her into a loving companion home instead.

This was not because she was “less valuable” as a dog.

She was deeply loved.

However, we did not feel comfortable placing additional physical strain on her cardiovascular system through pregnancy, whelping, nursing, and reproductive demands after a heartworm infection.

One of the difficult realities with heartworm disease is that you do not always know how long the infection existed before diagnosis or what degree of microscopic damage may already have occurred.

Even after successful treatment, there can still be lasting changes within the heart, lungs, or pulmonary vessels.

For us, choosing not to breed her was a decision rooted in caution, responsibility, and respect for her long-term well-being.

And we have never regretted making that choice.

Our Philosophy: Prevention Matters More Than Panic

Experiencing heartworm personally did not push us toward fear-based medicine.

Instead, it pushed us toward informed, balanced prevention.

At Vom Geliebten Haus, we believe deeply in combining:

• veterinary science,

• practical management,

• routine testing,

• environmental awareness,

• and holistic support.

We do not believe in ignoring heartworm risk.

But we also do not believe in blindly overloading dogs with unnecessary chemicals year-round without thought or strategy.

Like many experienced dog owners and breeders, we try to approach prevention thoughtfully and intentionally.

Our Current Heartworm Prevention Approach

1. Routine 4DX Testing

All of our dogs receive routine 4DX testing.

This test screens for:

• Heartworm disease

• Lyme disease

• Ehrlichia

• Anaplasmosis

We strongly believe testing matters.

Even owners who use preventatives consistently should test regularly because no prevention method is 100% foolproof.

Early detection can make a massive difference.

2. Seasonal Ivermectin-Based Prevention

We do believe in ivermectin-based prevention protocols.

However, we do not personally administer preventatives continuously during the coldest winter months when mosquito activity in our region is essentially nonexistent.

Instead, we approach prevention seasonally and strategically based on:

• climate,

• freezing temperatures,

• mosquito activity,

• and actual environmental exposure.

This is a personal management decision made carefully and responsibly.

Every owner should discuss regional risks and prevention timing with their veterinarian.

3. Holistic and Natural Mosquito Reduction

We also strongly believe prevention starts with the environment itself.

Heartworm cannot spread without mosquitoes.

So reducing mosquito exposure naturally is an important layer of protection.

Some of the things we focus on include:

• Eliminating standing water

• Proper drainage around kennel areas

• Keeping outdoor areas clean

• Avoiding heavy mosquito exposure during peak dawn/dusk hours

• Natural airflow and ventilation

• Outdoor fans in kennel areas

• Herbal and natural support approaches

• Maintaining strong overall immune health

No natural protocol alone guarantees protection.

That is important to say clearly.

But we believe holistic measures can absolutely help reduce overall mosquito pressure and support healthier dogs.

Supporting Overall Wellness Holistically

Our philosophy has always been that healthier dogs generally handle life stressors better overall.

That means focusing on:

• quality nutrition,

• healthy body condition,

• species-appropriate exercise,

• reduced toxic load,

• clean environments,

• stress reduction,

• and strong immune support.

We often incorporate natural approaches such as:

• whole food nutrition,

• herbal support,

• omega fatty acids,

• fresh air and outdoor movement,

• gut health support,

• and minimizing unnecessary overmedication whenever possible.

Holistic care is not about rejecting veterinary medicine.

It is about supporting the whole dog while still respecting science and medical reality.

And our heartworm experience reinforced exactly that balance.

Imported Dogs and Hidden Risks

Another important point many people do not realize:

Imported dogs can carry diseases that were not previously detected.

This does not necessarily mean anyone acted irresponsibly.

Sometimes infections are simply too early to detect at the time of export testing.

Sometimes timing matters.

Sometimes dogs come from regions with different prevalence levels.

Sometimes there are gaps between testing, transport, and arrival.

This is why post-import veterinary evaluation is absolutely critical.

Every imported dog entering a breeding program or home should receive thorough veterinary examination and testing after arrival.

What We Want Owners To Take Away From This

If there is one thing we hope people understand after reading this, it is this:

Heartworm prevention should never come from fear alone.

And it also should never come from denial.

There is a balanced middle ground.

The risk may be small. But it is never zero.

We know that personally.

We lived it.

And because of that experience, we now approach prevention with both realism and responsibility.

We believe in:

• testing,

• awareness,

• thoughtful prevention,

• holistic support,

• mosquito management,

• and informed decision-making.

Most importantly, we believe owners deserve honest conversations — not shame, panic, or extremes.

Our imported girl survived. She thrived. She was loved deeply. And although her journey into our lives did not go as originally planned, she still taught us lessons that shaped our kennel permanently.

Sometimes the hardest experiences become the ones that educate us the most
