Abstract

This report describes some of the characteristics of a cardiomyopathy in English Cocker Spaniels. Forty‐nine dogs from a kennel with a history of a cardiomyopathy were assessed clinically, electrocardiographically and radiographically. Angiography, haemodynamic and post‐mortem examinations were carried out on selected dogs. On electrocardiographic (ECG) and radiographic criteria the dogs were classified into five groups. Twenty‐six dogs (Group 1) were normal. Seven dogs (Group 2) showed ECG changes compatible with left or biventricular hypertrophy in the absence of radiographic abnormality. This was interpreted as concentric hypertrophy. Seven dogs (Group 3) showed ECG and radiographic evidence of cardiac hypertrophy with five of the seven exhibiting enlargement of both chambers. The changes were considered to be compatible with eccentric hypertrophy. Post‐mortem findings in dogs with ECG characteristics of Groups 2 and 3 have shown concentric hypertrophy in three cases and eccentric hypertrophy in one case. Six dogs (Group 4) had right axis deviations. Three dogs (Group 5) showed left axis deviations. It is suggested that a cardiomyopathy exists in English Cocker Spaniels initially developing as a concentric hypertrophy and progressing to eccentric hypertrophy. At present the aetiology is unknown.
