Protecting Your Pets in Hastings, MN from a Silent Threat

At Town & Country Veterinary Services in Hastings, MN, we often see well-meaning pet owners shocked to learn that their otherwise healthy dog is dealing with a potentially deadly parasite: heartworm. Many people assume it’s a “southern state” issue—but that couldn’t be further from the truth. Heartworm in dogs and cats is a very real concern in Minnesota, and it’s our job as veterinarians to keep your furry besties safe.

If you’ve Googled “vet near me” recently because your pup has a cough or seems off, it’s time to consider heartworm testing. Our veterinary clinic offers diagnostics, year-round heartworm protection, and expert care plans to help your pet avoid this life-threatening disease.

What Is Heartworm and How Does It Spread?

Heartworm disease is caused by a parasitic worm, Dirofilaria immitis, which is spread through mosquito bites. When an infected mosquito bites your pet, it can deposit microscopic larvae into the bloodstream. These larvae eventually mature into adult worms that live in the heart, lungs, and blood vessels.

A single mosquito bite is all it takes.

The disease affects both dogs and cats, though it behaves differently in each species. In dogs, it’s more common and usually more severe—but don’t let that fool you. Cats can suffer sudden death from even one adult worm.

Recognizing the Signs of Heartworm in Pets

The tricky part about heartworm is that early symptoms are subtle—or even nonexistent. That’s why regular screenings at our Hastings, MN veterinary clinic are essential. Watch for these signs of heartworm in pets:

In dogs:

• Persistent cough
  
• Fatigue after moderate activity
  
• Weight loss
  
• Swollen belly (from fluid buildup)
  
• Labored breathing
  

In cats:

• Asthma-like attacks or coughing
  
• Vomiting (unrelated to eating)
  
• Gagging
  
• Loss of appetite
  
• Sudden collapse or death
  

Because cats often show atypical symptoms or no symptoms at all, it’s vital to include heartworm prevention medication in their routine care, even if they’re indoor-only. Learn more about heartworms and associated symptoms at the American Heartworm Society here.

Heartworm Prevention Medication: What You Need to Know

Here’s the good news: heartworm disease is completely preventable.

There are several heartworm prevention medications available, and at Town & Country Veterinary Services, we’ll help you choose the best option for your pet’s age, lifestyle, and species. These include:

• Monthly oral preventives (chewables or tablets)
  
• Topical treatments (applied to the skin)
  
• Injections (lasting 6–12 months, for dogs)
  

These medications also often protect against other parasites like roundworms and hookworms—a win-win for your furry friend.

Prevention must be consistent. Missing just one dose can leave your pet vulnerable. We recommend year-round heartworm protection for pets in Hastings, MN due to shifting weather patterns and indoor mosquito exposure.

Why Year-Round Heartworm Protection Is Critical

Some pet owners mistakenly believe they only need to give heartworm prevention during the summer. While it’s true that mosquitoes are more active then, here’s why year-round prevention is a must:

• Mosquitoes can survive in homes, garages, and basements even during the colder months.
  
• Giving year-round prevention builds a reliable habit—you won’t accidentally forget.
  
• Monthly preventives also protect against intestinal parasites, which are a year-round threat.
  

Think of it as insurance. Year-round heartworm protection saves lives and prevents heartbreaking (and costly) emergencies.

How We Diagnose and Treat Heartworm at Our Hastings Vet Clinic

Diagnosis in dogs:
We perform a simple blood test during your dog’s wellness exam to detect heartworm antigens. If positive, further tests are done to confirm the extent of the infection.

Diagnosis in cats:
Diagnosis is more complicated in cats and may include blood tests, X-rays, and ultrasound. Sadly, there is no approved treatment for adult heartworms in cats, which is why prevention is so crucial.

Treatment in dogs:
Treatment is possible but intensive. It involves medications to kill adult worms, strict exercise restriction, and months of monitoring. In some cases, surgery may be required. It’s expensive, stressful for you and your pup, and avoidable with prevention. PetMD has an article explaining the various options for heartworm treatment here.

Treatment in cats:
Since we can’t eliminate adult worms safely, our veterinarians focus on managing symptoms and minimizing complications.

FAQs About Heartworm

How often should my pet be tested for heartworm?

Dogs should be tested annually. Cats should be tested before starting prevention and monitored regularly.

My dog stays inside—do I still need prevention?

Yes. Mosquitoes get into houses all the time. One bite is all it takes.

Can my puppy or kitten start heartworm prevention right away?

Yes! Puppies can begin preventive meds by 6–8 weeks old. Kittens can begin shortly after weaning. We’ll guide you.

Is heartworm treatment painful for dogs?

It can cause discomfort, especially as worms die off. That’s why close supervision and rest are critical.

Why Local Care Matters: Hastings, MN and Your Pet’s Risk

Even though Minnesota is not a high-risk state like Louisiana or Texas, cases of heartworm in dogs and cats do occur here—especially in areas near water, wooded environments, and during warmer months.

Mosquitoes thrive along the Mississippi River, wetlands, and parks in and around Hastings, MN. With more unpredictable weather and warmer winters, mosquito activity can start earlier and last longer than you might expect.
