The breed can influence the results of haematological and biochemical blood tests, with sighthounds traditionally mentioned. It may also affect certain urinary parameters. This study aimed to compare urinary protein and creatinine concentrations and their ratio (UPC, urine protein to creatinine ratio) between sighthounds and non-sighthounds and to evaluate these parameters in various sighthound breeds. Urine samples from clinically healthy dogs were collected via normal voiding, representing both sighthound and non-sighthound breeds. The protein and creatinine concentrations in the urine samples were determined, and their ratio was subsequently calculated. A total of 191 urine samples from sighthounds and 90 urine samples from non-sighthound breeds used as a control group were evaluated in the study. In sighthounds, significantly lower urinary protein concentration (248.8 mg/l and 299.8 mg/l, respectively; P = 0.045) and significantly higher urinary creatinine concentration (23.0 mmol/l and 17.5 mmol/l, respectively; P = 0.000) and lower UPC values (0.13 and 0.18, respectively; P = 0.000) were observed in comparison to the entire control group. The UPC values were found to be significantly lower in Greyhounds and Spanish Greyhounds compared with non-sighthounds. Although statistically significant changes were identified, they are unlikely to be of great clinical importance.
