This study aimed to establish baseline hematobiochemical and cardiac biomarker parameters in clinically healthy Labrador Retrievers and assess the influence of body weight on these indices. Sixteen adult Labrador Retrievers (2–6 years, both sexes) were categorized into two groups based on body weight: Group-I (<30 kg) and Group-II (>30 kg). Comprehensive evaluations including hematological, biochemical, and cardiac biomarker analyses were performed following confirmation of the dogs' health status. Hematological parameters including hemoglobin, packed cell volume, RBC, WBC and platelet counts, as well as biochemical parameters such as AST, ALT, total protein, albumin, BUN and creatinine were within normal ranges with no significant intergroup differences. Cardiac biomarker analysis revealed cTnI levels of 0.0056±0.0014 ng/mL in Group-I and 0.0081±0.0018 ng/mL in Group-II, while NT-proBNP levels were 1.9731±0.3085 pmol/L and 3.0789±0.8485 pmol/L, respectively. These differences were not statistically significant indicating stable cardiac health across varying body weights. This study provides valuable baseline data on hematobiochemical and cardiac biomarker parameters in Labrador Retrievers emphasizing the minimal impact of body weight on these indices and contributing to improved cardiac health assessment in this breed.
