Retrospective study of heart disease in miniature poodles.
Myxomatous mitral valve disease (MMVD) is the most common cardiovascular disease in the dog. A study examined the records of thirty-two miniature poodles with MMVD.
Findings are highlighted below:
The mean age of the dogs when diagnosed was 11 years.
Clinical signs included exercise intolerance, syncope and coughing.
Eighteen dogs were classified as ACVIM Stage B1, 12 as stage B2, and two as stage C.
Only one dog had radiographic evidence of congestive heart failure.
Mean diastolic left ventricle dimension normalized to body weight was 1.6 (±0.4) and mean systolic was 0.8 (±0.3).
Mitral valve prolapse was subjectively classified as mild or moderate in 19 dogs and severe in two.
