Heart Inflammation (Myocarditis) in Dogs




Dogs with severe myocarditis, congestive heart failure (CHF), or severe heart rhythm problems may need to be hospitalized for intensive care and treatment. If specific causative organism is identified, infection will be treated with suitable medicine, such as antibiotics to fight off bacterial infections. There are also medications to correct heart rhythym issues, should the dog be suffering from them. In some patients, a pacemaker may need to be implanted.


Living and Management


The overall prognosis for myocarditis depends on the extent and severity of disease. Dogs with CHF as a result of myocarditis, for example, have very poor prognosis, while those with milder forms of the disease respond well to treatment.


You will need to visit your veterinarian regularly for follow-up evaluation and frequent laboratory testing will be conducted to monitor progress and response to treatment. Limiting your dog's activity is important for recovery, as well as setting aside a quiet place for it to rest, away from household activity, children, and other pets.


Certain diet restrictions may be recommended, especially those concerning your dog's salt intake.
