    The study was carried out in Labrador retriever breed of dogs to study the influence of right and left lateral recumbency on Vertebral Heart Score. Twelve Labrador retriever dogs of either gender were selected for the study and divided into two groups, A and B consisting of six dogs each. Group A included six normal Labrador retriever dogs and Group B included six Labrador retriever dogs with established cardiac disorders. The overall occurrence of cardiac disorders among the dogs was 1.94% with Labrador retrievers represented the highest occurrence of cardiac diseased dogs (24.84%) in one year study period. The middle aged (4-8 years) dogs were overrepresented (43.63%) followed by old dogs (> 8 years) (35.15%) and the least occurrence was in young dogs (0-4 years) (21.21%). Male Labrador retrievers had higher occurrence than female ones. VHS in Group A dogs was 10.1 ± 0.03v and 9.8 ± 0.03v in right and left lateral recumbency respectively. VHS in Group B dogs was 11.8 ± 0.17v and 11.3 ± 0.18v in right and left lateral recumbency respectively. The VHS of Group B dogs was significantly greater than the Group A dogs. The VHS in right lateral recumbency was significantly greater than left lateral recumbency. The ECG parameters varied non significantly between the groups but comparable alterations were noticed. The echocardiography showed significantly increased LVIDd, LVIDs, EDV, ESV and LA/Ao ratio and significantly decreased EF (%) and FS (%) between the groups. The VHS was subjectively correlated well with the ECG and echocardiographic parameters for Labrador retriever breed of dogs. Finally, based on observations and evaluations, it could be concluded that the combination of all three techniques was helpful in assessing the severity and significance of heart diseases and useful to evaluate the therapeutic efficiency.
