Canine prostatic‐specific esterase and prostatic ultrasound correlation in dogs: diagnostic value, influence of castration and clinical cut‐off proposal

Serum canine prostate-specific esterase concentration is a promising non-invasive biomarker for evaluating prostatic status in male dogs. However, interpretation must consider body size and reproductive status. Its integration into routine screening could improve early detection and monitoring of prostatic changes, particularly in high-risk groups.
