Results of urinalysis and bacterial culture of urine specimens obtained during midstream voiding, by catheterization, and by cystocentesis were studied in 50 clinically normal dogs (25 females and 25 males). All of the specimens obtained by cystocentesis were bacteriologically sterile. Bacterial growth occurred in 26% of the catheterized specimens and in 85% of the voided specimens. The proportion of positive urine cultures from catheterized and voided specimens was higher for females than for males. Results or urinalysis did not correlate well with results of bacterial culture.
