Case report: anaplasma-related myocardial damage in a dog.

We present the case of a female dog that was evaluated following an episode of heart failure and was subsequently diagnosed with anaplasmosis. Cardiac assessment revealed evidence of myocardial injury, systolic dysfunction, and conduction system abnormalities. This case highlights the importance of considering infection as a potential cause of myocarditis, especially in instances of unexplained heart failure and elevated troponin levels in the absence of other underlying conditions.
