OBJECTIVES: The main goals of this study were (1) to carry out a retrospective study of the prevalence of left apical systolic heart murmurs, which are considered to clinically reflect the presence of MVD, in the 6 small canine breeds most popular in France, i.e., Yorkshire Terrier, Bichon Maltese, Dachshund, Poodle, Lhassa Apso and Shi Tzu and (2) to compare the results with those obtained in a recent report published by our group on MVD in 451 CKC. BACKGROUND: Mitral valvular disease (MVD) has been extensively studied in Cavalier King Charles spaniels (CKC) but seldom studied and compared in other small-breed dogs. The first clinical sign of MVD is the early appearance of a left apical systolic heart murmur. ANIMALS: Nine hundred and forty-two adult dogs were included in the present study (mean+/-SD, age=6.5+/-4.4 years, weight=6.2+/-2.6kg). RESULTS: The average total prevalence of left apical systolic heart murmur was 14.4% compared with 40.6% in CKC. It was significantly more prevalent in males (18.5%) than in females (9.8%). Shi Tzu and Dachshunds were the most affected breeds investigated. Most (81%) of the dogs with left apical systolic murmur were classified in ISACHC heart failure class I. CONCLUSION: This large retrospective study suggests that the prevalence of MVD is higher in CKC than in the 6 small breeds investigated. Moreover, most of the dogs do not develop congestive heart failure.
