Pit bull-type breeds with dilated cardiomyopathy eating nontraditional diets improve after diet change (2015-2022).

Objective: To compare signalment, clinical signs, diet, echocardiographic findings, and outcome for pit bull-type breeds diagnosed between 2015 and 2022 with dilated cardiomyopathy (DCM) or with DCM diagnosed by a cardiologist but that did not meet all study echocardiographic criteria (DCM-C).

Animals: 91 dogs with DCM and 11 dogs with DCM-C.

Procedures: Data were collected on clinical findings, echocardiographic measurements, and diet at the time of diagnosis (for 76/91 dogs); echocardiographic changes; and survival.
