As pet parents, we’re always watching out for our furry friends—whether it’s hiding the chocolate, checking for ticks, or baby-proofing the house to keep the dog out of the trash (again). But there’s one threat that’s nearly impossible to see… until it’s too late.
Let’s talk about heartworms—the sneaky, serious, and 100% preventable condition that every pet owner needs to have on their radar.
So, What Are Heartworms?
Heartworms are exactly what they sound like: parasites that live in the heart and lungs of your dog or cat. They’re spread by mosquitoes (yes, those annoying buzzing things we all hate), and once bitten, it takes just ONE tiny larva to grow into a spaghetti-like adult worm—up to a foot long!
In dogs, they hang out in the heart and lungs, causing coughing, fatigue, and eventually heart failure if untreated. In cats, even one or two worms can cause severe respiratory issues—or sudden death.
“But My Pet Is Mostly Indoors…”
We hear this all the time. But here’s the truth: it only takes one mosquito bite. And mosquitoes? They’re sneaky too. They’re looking for a meal, they don’t care if your pet goes to daycare or just naps in sunbeams by the window. In fact, we’ve diagnosed heartworm disease in plenty of dogs and cats who rarely set a paw outside.
What Heartworm Disease Looks Like
Heartworm disease can be a silent killer. Many dogs don’t show signs until the disease is advanced. Symptoms may include:
- Mild, persistent cough
- Reluctance to exercise
- Fatigue after moderate activity
- Decreased appetite
- Weight loss
- Swollen belly from fluid buildup
In cats, the signs can be even more vague—vomiting, trouble breathing, or just suddenly collapsing.
The Real Heartbreaker: Treatment vs. Prevention
Here’s the kicker: treating heartworms is expensive, risky, and hard on your pet. For dogs, it involves injections, strict rest (no zoomies!), and months of recovery. For cats, there’s no approved treatment at all—we can only manage symptoms and hope for the best.
But the good news? Heartworm disease is completely preventable.
Monthly preventives—whether chewables, topicals, or injections—are safe, effective, and affordable. We’re talking less than the cost of a monthly coffee habit, and way less than the thousands it might cost to treat full-blown heartworm disease.
For their safety, your pet will need a yearly heartworm test to verify they are negative for heartworms before we prescribe more prevention, even if your pet has never missed a dose. As silly as that sounds, if your pet does test positive while they have been on year-round prevention, and you purchased the prevention from us directly or from our online pharmacy, we will work with the manufacturer and may be able to get your pet the treatment they need without any cost to you.
Real Talk: “Do I Really Need to Give It Year-Round?”
Yes. Even in winter. Even if you haven’t seen a mosquito in months. Why?
- Mosquitoes can survive indoors.
- Climate is unpredictable—warm snaps happen.
- Prevention only works if it’s consistent.
Think of it like brushing your teeth. Skipping a few days might not cause a cavity right away… but over time, the risk builds up.

We love our pets like family. They trust us to keep them safe—whether it’s choosing the right food, giving belly rubs after a scary thunderstorm, or making sure they’re protected from diseases we can’t even see.
