Endocarditis in dogs is an infection or inflammation of the lining of the inner surface of the heart, known as the endothelium. Sometimes this condition is referred to as endocardioscan be.
Usually it’s the result of a bacterial infection, although fungal infections may also cause the infection in dogs. Endocarditis is uncommon, which means vets sometimes overlook or misdiagnose it, and this is particularly dangerous because the condition is often fatal if it goes untreated.
Sometimes the condition is accompanied by myocarditis and pericarditis, creating further complications.
The disease appears more often in older dogs and male dogs, and it can occur in any breed, though larger breeds are more at risk. While dogs may fight off the infection with treatment, the damage done to the heart is often irreversible.
If you see the signs of endocarditis in your dog, then you must consult your veterinarian for a proper diagnosis and treatment. The earlier treatment begins, the better. Here’s what you should know about the symptoms, causes, and treatments for endocarditis in dogs.
Symptoms Of Endocarditis In Dogs
The symptoms of endocarditis in dogs usually develop fairly quickly, as diseases that affect the function of the heart tend to affect the entire body. Often the signs of endocarditis are similar to the signals of left-sided congestive heart failure.
Here are several possible signs to watch out for in dogs:
- Coughing
- Breathing difficulty
- Exercise intolerance
- Weakness
- Fatigue
- Weight loss and anorexia
- Ascites (fluid in the abdomen)
- Fever
- Heart murmur
- Arrhythmia
- High blood pressure
- Collapse
Causes Of Endocarditis In Dogs
Endocarditis in dogs is usually caused by bacterial infection, which may begin elsewhere in the body and move to the heart through the bloodstream. Rickettsia, Bartonella, and fungal infectionss may rarely be the cause.
Sometimes surgical procedures, immunosuppressive medical treatments, and cancer can increase the risk of endocarditis. Endocarditis can lead to blood clots, abnormal heart function, and eventually heart failure.
Dogs with weakened immune systems are more susceptible to infection. Any kind of pre-existing heart condition can also increase the risk that endocarditis will develop.
Treatments For Endocarditis In Dogs
There is a reasonable chance that treatment for endocarditis in dogs will lead to recovery if the condition is caught and treated early, though it’s highly fatal if treatment is delayed.
Treatment usually begins with a course of antibiotics to fight bacterial infection, and vets could also prescribe anti-arrhythmic drugs to treat heart beat abnormalities.
If the condition has progressed, then vets may prescribe drugs to treat congestive heart failure, as well. These include diuretics to reduce fluid buildup, vasodilators to loosen blood vessels, and enzyme inhibitors. At this stage, the damage is normally irreversible, and the prognosis is not good.
Prevention can go a long way. Bacteria often enters through the mouth, so proper oral care frequently helps ward off endocarditis and other infectious conditions. Regular veterinary teeth cleanings and at-home brushing are essential.
Dogs who suffer from other heart conditions, oral infections, or immunosuppressive conditions may need treatment with antibiotics before and after dental cleanings.
Take steps to keep your dog’s immune system healthy, and their overall ability to fight off infection will improve.
