How Long Can A Dog Live With Heartworms Untreated


Heartworm disease is a serious and potentially life-threatening condition that can affect dogs who are not on a regular preventative medication. If left untreated, heartworms can cause severe damage to a dog’s heart, lungs, and blood vessels, ultimately leading to heart failure and death. In this article, we will explore the question: how long can a dog live with heartworms untreated?

To start, it’s important to understand how heartworms affect a dog’s body. Heartworms are transmitted through the bite of an infected mosquito. Once inside a dog’s body, the worms grow and reproduce, eventually causing blockages in the heart and blood vessels. This can lead to symptoms such as coughing, fatigue, and difficulty breathing. If left untreated, heartworm disease can be fatal.

One of the most concerning aspects of heartworm disease is the fact that it can go unnoticed for a long time. Dogs may not show any symptoms in the early stages of the disease, making it difficult for pet owners to know that their dog is infected. This is why regular screenings and preventative medications are so important in keeping dogs healthy.

In terms of how long a dog can live with heartworms untreated, the answer is not straightforward. The length of time can vary depending on factors such as the dog’s age, overall health, and the severity of the infection. However, in general, dogs with untreated heartworm disease have a much shorter life expectancy than those who receive treatment.

To shed more light on this topic, we reached out to several professionals in the field for their insights. According to a veterinarian, “Untreated heartworm disease can be devastating for dogs. The longer the disease goes untreated, the more damage it can cause to the heart and lungs. In severe cases, dogs may only have a few months to live.”

A veterinary technician added, “It’s heartbreaking to see dogs suffering from heartworm disease. Many pet owners are unaware of the dangers of heartworms and may not realize the importance of preventative measures. Regular screenings and preventative medications are essential in keeping dogs healthy and happy.”

A veterinary assistant chimed in, saying, “I’ve seen firsthand the toll that heartworm disease can take on dogs. It’s a painful and debilitating condition that can greatly reduce a dog’s quality of life. Early detection and treatment are key in preventing the progression of the disease.”

Lastly, a pet groomer shared their perspective, stating, “As a pet groomer, I often see dogs who are suffering from heartworm disease. It’s a heartbreaking situation that could have been prevented with regular preventative care. Pet owners need to be proactive in protecting their furry friends from this deadly disease.”

Now, let’s address some common concerns and questions related to how long a dog can live with heartworms untreated:

1. Can heartworms go away on their own?

No, heartworms cannot go away on their own. Without treatment, the worms will continue to grow and multiply, causing further damage to a dog’s organs.

2. How long does it take for heartworms to kill a dog?

The progression of heartworm disease can vary, but in severe cases, it can lead to death within a few months.

3. Can heartworms be transmitted to humans?

No, heartworms are not transmissible to humans. They can only be transmitted through the bite of an infected mosquito.

4. What are the symptoms of heartworm disease in dogs?

Symptoms of heartworm disease can include coughing, fatigue, difficulty breathing, and weight loss.

5. How is heartworm disease diagnosed?

Heartworm disease is diagnosed through a blood test that detects the presence of heartworm proteins in a dog’s bloodstream.

6. What is the treatment for heartworm disease?

Treatment for heartworm disease typically involves medication to kill the adult worms, as well as strict rest and monitoring to prevent complications.

7. Can heartworm disease be prevented?

Yes, heartworm disease can be prevented through regular screenings and preventative medications prescribed by a veterinarian.

8. Are certain dog breeds more susceptible to heartworm disease?

While all dogs are at risk for heartworm disease, certain breeds may be more susceptible due to genetic factors. It’s important for all dogs to receive preventative care.

9. Can indoor dogs get heartworm disease?

Yes, indoor dogs are still at risk for heartworm disease if they are not on a regular preventative medication. Mosquitoes can still find their way inside homes and transmit the disease.

10. Can heartworm disease be passed from mother to puppies?

Yes, mother dogs can pass heartworm disease to their puppies through their blood. It’s important for pregnant dogs to be screened for heartworms and receive appropriate treatment.

11. Can heartworm disease be fatal in puppies?

Yes, heartworm disease can be fatal in puppies if left untreated. Puppies are more vulnerable to the effects of heartworms due to their smaller size and developing immune systems.

12. Can heartworm disease be cured?

While treatment can eliminate adult heartworms from a dog’s body, the damage caused by the disease may be irreversible. It’s important to catch the disease early to prevent complications.

13. Can heartworm disease be transmitted through saliva?

No, heartworm disease is not transmitted through saliva. It can only be transmitted through the bite of an infected mosquito.

14. Can heartworm disease cause behavioral changes in dogs?

Yes, the pain and discomfort caused by heartworm disease can lead to changes in a dog’s behavior, such as increased aggression or lethargy.

15. Can heartworm disease recur in dogs who have been treated?

While treatment can eliminate adult heartworms, dogs who have been infected are still at risk for re-infection if they are not on a regular preventative medication.

In summary, the question of how long a dog can live with heartworms untreated is a complex one. While the exact timeline can vary, it’s clear that untreated heartworm disease can have severe and potentially fatal consequences for dogs. Regular preventative care, including screenings and medications, is essential in protecting our furry friends from this deadly disease. Remember, early detection and treatment are key in ensuring a long and healthy life for our canine companions.
