In diagnosing canine urinary issues, what collection method is preferred for accurate urine cultures?

Explanation:
Direct sampling from the bladder with cystocentesis provides the most accurate urine culture because it bypasses the urethra and external/genital areas, yielding a sterile sample and minimizing contamination from normal flora present on the skin or distal urinary tract. Free catch and manual expression are more prone to skin, vulvar/vaginal, or urethral contamination, and catheterization can introduce bacteria from the distal urethra. Therefore, cystocentesis is the preferred method for obtaining a urine culture in dogs.
