The capillary refill time (CRT) for Buddy is 1 second. The chart records the CRT as:

• A. Abnormally high
• B. Normal
• C. Abnormally low
• D. Not enough information to record

Answer: (B)

Capillary refill time gauges peripheral perfusion by pressing on a mucous membrane and timing how quickly color returns. In dogs, a normal CRT is generally about 1 to 2 seconds. A 1-second CRT shows adequate perfusion, so it should be recorded as normal. If CRT were longer than this—typically over about 2 seconds—that would be considered abnormally high, indicating reduced perfusion. A CRT significantly shorter than normal would be abnormally low, though that situation is less commonly a clinical concern. Since you have a precise 1-second measurement, there is enough information to classify it as normal.
