Indoor Dogs and Heartworm Disease: Are They Really Safe?

When it comes to protecting our furry friends against parasites, most dog parents believe that simply keeping them indoors will protect them from all dangers. However, that’s far from the truth, especially for heartworm disease. Heartworms are transmitted through mosquito bites, and these pesky insects can easily find their way into your homes.

Moreover, unlike fleas and ticks, heartworms are not visible to the naked eye and can go undetected for a long time. You won’t see the disease coming, and by the time you recognize the illness, it might be too late for your beloved pooch.

Therefore, it’s crucial to protect your dog against heartworms regardless of the environment. In this blog, we’ll understand the fundamentals of heartworm disease, common symptoms, and the importance of heartworm prevention.

Let’s start with the fundamentals!

What is Heartworm Disease in Dogs?

Heartworm disease is a potentially fatal condition that is caused by a parasite called Dirofilaria immitis. The parasite enters the dog when an infected mosquito carrying the heartworm larvae, bites the dog and transmits heartworm larvae (microfilariae). These worms grow up to a foot long or more and live inside the heart, lungs, and associated blood vessels.

Over time, the infected dog can suffer from severe lung disease, heart failure, and damage to the other organs. If left untreated, heartworm disease can be fatal for your dog, making prevention a top priority for dog parents.

Common Symptoms of Heartworm Disease

Here are the tell-tale signs of heartworm disease in dogs:

• Persistent Cough
• Lethargy and reluctance to exercise
• Weight loss
• Breathing difficulties
• Collapse
• Sudden collapse or death

Do Indoor Dogs Need Heartworm Prevention?

Yes, absolutely! Even if your dog stays inside most of the time, they are still not fully protected against the risk of heartworm disease. Even a single bite from an infected mosquito can transmit the parasite, and mosquitoes can easily find their way into your home.

Moreover, your dog will still go outside sometimes, be it for walks, bathroom breaks, or playtime. In such cases, your dog is exposed to mosquitoes and is at risk of contracting heartworm disease, making prevention imperative.

Preventive Tips to Protect Your Dog from Heartworm Disease

Now that you know how crucial it is to protect your pooch against heartworms even if they stay indoors, let’s dive into some practical tips to keep your furry friend safe.

• Keep up regular visits to your vet and practice regular heartworm testing for early detection.
• Use year-round prevention as recommended by your vet and stay consistent with doses.
• Use preventive treatments such as Advantage Multi, Comfortis Plus, or Heartgard Plus.
• Reduce your dog’s exposure to mosquitoes with screens on windows and doors.
• Keep your yard and surroundings clean, plus clear standing water.
• Keep up with the flea and tick treatments.
• Use mosquito traps and pet-safe repellents in spaces where your dog spends time.
