Infective Endocarditis in Dogs Understanding Infective Endocarditis in Dogs

Infective Endocarditis in Dogs

Infective Endocarditis (IE) is a serious heart disease that affects dogs. We discuss the condition more in this article.

What is Endocarditis?

Endocarditis is a grave and potentially life-threatening condition that can affect dogs. This condition occurs when bacteria or other microorganisms enter the bloodstream and infect the heart's inner lining causing inflammation of heart valves. While rare, Infective Endocarditis can have serious consequences for a dog's health, leading to heart failure or other complications. 

In this article, we will provide an overview of Infective Endocarditis in dogs, including its causes, symptoms, treatment, and preventive tips.

Endocarditis Causes

The causes of Infective Endocarditis in dogs can be diverse, but the leading factor is the presence of bacteria or other microorganisms in the bloodstream. Here are a few causes of mitral valve endocarditis in dogs:

  • Bacterial infection: A bacterial infection is the most frequent reason for Infective Endocarditis in dogs. An open wound or an infected location can allow it to get into the bloodstream.

  • Dental conditions: Untreated dental conditions and poor oral hygiene can result in bacterial infections that travel to the heart and result in Infective Endocarditis.

  • Foreign objects: If a dog swallows one or if a sharp object pierces the skin, it may infect the heart and result in Infective Endocarditis.

  • Immune system disorders: Infections that can lead to Infective Endocarditis are more likely to affect dogs whose immune systems are already compromised, such as those with autoimmune diseases or those receiving chemotherapy.

  • Catheterization: The insertion of catheters into the veins or arteries of dogs, such as those receiving dialysis or blood transfusion.

  • Heart disease: Dogs that already have cardiac issues like mitral valve dysfunction are more likely to get infectious endocarditis.

Endocarditis Symptoms

The signs of Infective Endocarditis in dogs can be subtle and can develop over time, making it difficult to diagnose the condition. The symptoms can also vary depending on the gravity of the infection and which part of the heart is affected. Here are some of the prevalent symptoms of Infective Endocarditis in dogs:

  • Appetite loss

  • Weight loss

  • Lethargy and weakness

  • Fever

  • Coughing

  • Rapid breathing or shortness of breath

  • Abdominal distension or bloating

  • Lameness or difficulty walking

  • Joint pain 

  • Heart murmurs or abnormal heart sounds

  • Arrhythmia

  • Pale or bluish gums

  • Seizures or other neurological symptoms

Treatment and Management Options

The treatment and management of mitral valve endocarditis in dogs can depend on several factors, such as the severity of the infection, the extent of heart damage, and the particular cause. The following are some of the most popular forms of care for canine infectious endocarditis:

  • Antibiotics: The primary treatment for mitral valve endocarditis in dogs is a course of antibiotics to eliminate the infection. Medications like Doxycycline or Clavamox may be prescribed based on the particular infection diagnosed.

  • Supportive care: Dogs with Infective Endocarditis may require supportive care to manage their symptoms, such as pain relief medications, fluid therapy, and oxygen therapy. In some cases, dogs may also require hospitalization.

  • Surgery: In extreme situations of Infective Endocarditis, surgery may be required to replace or repair damaged heart valves or to remove infected tissue.

  • Follow-up care: In order to be sure that the infection has been entirely eradicated and to manage any long-term consequences on the heart, dogs with infectious endocarditis will need continuous monitoring and follow-up treatment. This might involve routine cardiac monitoring, imaging exams, and blood testing.

Preventive Tips

It can be difficult to prevent Infective Endocarditis in dogs, but there are numerous measures you can do to lower your dog's risk of getting the ailment. Here is some helpful precautionary advice:

  • Good dental hygiene: Brushing your dog’s teeth regularly and using good dental products is a good step necessary to prevent this condition. Also, regular dental cleanings and exams can help prevent dental disease and reduce the risk of bacterial infections that can cause Endocarditis.

  • Preventing dangerous behaviors: Don't let your dog swallow strange things or expose them to unsafe water sources.

  • Immediate veterinarian care should be sought if your dog has an infection, especially if it is not healing or is recurring.

  • Frequent vet visits: Regular visits to your doctor can help identify any underlying health issues or dangers that can make your dog more vulnerable to Infective Endocarditis.

  • Proper nutrition: Providing your dog with a balanced and nutritious diet can help strengthen its immune system and reduce its risk of infections.

  • Vaccinations: Ensure your dog is up-to-date on all vaccinations, including those for common bacterial infections.

Endocarditis prognosis is generally not good, but following these preventive tips can help reduce your dog's risk of developing Infective Endocarditis and keep them healthy and happy for years to come.
