The best urine sample from a housebroken dog for collection is typically collected when?

• A. Late evening
• B. Afternoon
• C. Midmorning
• D. Early morning

Answer: (D)

Collecting urine first thing in the morning takes advantage of the dog having held urine overnight, which makes the sample more concentrated and a more stable representation of the kidneys’ function. A concentrated, early-morning sample is less influenced by recent meals, water intake, or activity, so the urinalysis and any measurements like specific gravity are more reliable. Options later in the day tend to be more variable because the dog has been eating, drinking, and exercising, which can dilute or alter urine composition. So the earliest morning collection provides the best, most consistent sample.
