Introduction
If you’re a caretaker of our four-legged friends, you’ve likely heard of the dreaded heartworm disease. In this piece, we’ll explore what heartworms look like in dogs, how they affect their health, and what you, their guardian, can do to prevent these parasites from causing harm.
Understanding Heartworms
Heartworms are parasites that live in the heart, lungs, and blood vessels of infected pets, causing severe lung disease, heart failure, and damage to other organs. They’re transmitted by mosquitoes, turning a simple mosquito bite into a life-threatening condition.
Imagine a spaghetti noodle. Now, picture that noodle wriggling around inside your dog’s heart. That’s what a heartworm looks like. They can grow up to a foot long, and an infected dog can host as many as 250 worms.
Symptoms of Heartworm Disease
You know how to identify heartworms visually now, but that’s of little use unless you’re a vet performing surgery. What you need to know are the signs your dog might be infected. These include:
- Mild persistent cough
- Fatigue after moderate activity
- Decreased appetite
- Weight loss
As the disease progresses, dogs may develop heart failure and the appearance of a swollen belly due to excess fluid in the abdomen.
Preventing Heartworm Disease
The good news is that heartworm disease is preventable. Here’s what you can do:
- Regular Testing: The American Heartworm Society recommends annual testing for all dogs.
- Preventative Medication: Many safe and effective heartworm preventatives are available.
The table below shows some common heartworm preventatives, their type, and frequency of use:
| Medication | Type | Frequency |
|---|---|---|
| Heartgard | Chewable | Monthly |
| Revolution | Topical | Monthly |
| ProHeart | Injection | Every 6 months |
Treating Heartworm Disease
If your dog is diagnosed with heartworms, don’t panic. Treatment is possible, though it’s expensive and can be hard on your dog. The goal is to first stabilize your dog’s condition, then kill all adult and immature worms.
Frequently Asked Questions

A: Yes, cats can get heartworms, but they are not as susceptible as dogs.
Q: Can heartworm disease be prevented?
A: Yes, heartworm disease is preventable with a monthly medication prescribed by your vet.
Remember, as a caregiver, you play a critical role in your dog’s health. By understanding what heartworms look like and how they affect your dog, you’re better equipped to prevent this deadly disease.
