The process of obtaining a free-catch urine specimen from a canine subject involves careful timing and, often, considerable patience. It is a non-invasive method used to gather fluid for diagnostic purposes. A suitable container is positioned to intercept the stream as the animal urinates.
The value of a properly collected sample lies in its ability to provide crucial information about the animals health. Accurate assessment of kidney function, detection of urinary tract infections, and identification of other metabolic abnormalities are all dependent upon the integrity of the specimen. Historically, this method has been preferred for its ease and lack of discomfort for the animal, provided it can be accomplished without undue stress.
