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.

OBJECTIVE: The aim of the study was to compare the haematological and biochemical profiles of eight sighthound breeds. DESIGN: Samples were taken from 192 individuals of the sighthound breeds (Whippet, Greyhound, Italian Greyhound, Sloughi, Saluki, Borzoi, Pharaoh Hound and Azawakh). Routine haematological and biochemical examinations were performed and the results were evaluated statistically. RESULTS: There were significant differences in haematology and clinical biochemistry among the sighthound breeds. The most similar laboratory profile to Greyhounds was found in Whippets. Italian Greyhounds had significantly higher alanine aminotransferase activity than other sighthounds, except Pharaoh Hounds. CONCLUSION: Application of the Greyhound laboratory profile to other sighthounds is not recommended because of the frequent differences in haematological and clinical biochemical reference intervals.

In the present study we determined the foetal growth curve of the greyhound. Using an LKB 2250 PMV cryomicrotome, we studied selected sagittal sections from 15 foetuses of the same breed of dog and described the expansion and development of the thoracic and abdominal cavities, the lungs, the liver and (in part) the heart and the thymus. Drawings of the sections were measured by means of a Vids II image analyser and its fractional area programme.

We describe the chronology of the development of the renal system and gonads of 19 greyhound foetuses. The smallest specimens were embedded in paraffin wax and were sectioned serially at 10 microns; the rest were sectioned at 50 microns in an LKB 2250 PMV cryomicrotome. Selected sections were stained with haematoxylin and eosin. The mesonephros, metanephros and gonads were measured in drawings of the sections, using the area fraction programme of a Vids II image analyse.

We describe the chronology of development of the stomach and intestine in 18 greyhound foetuses. Using an LKB 2250 PMV cryomicrotome, we obtained corresponding series of sections (50 microns). Very small specimens were embedded in paraffin wax and sectioned at 10 microns. Selected sections were stained with haematoxylin and eosin. For measurement, the fractional area programme of a Vids II image analyser was employed.
