Which of the following is NOT a key component of a canine physical examination?

A puppy training evaluation does not fit as a key component of a standard canine physical examination. The physical examination primarily focuses on assessing the dog's overall health and physical condition through various methods. This includes evaluating vital signs, such as heart rate and respiratory rate, which provide critical insights into the animal's physiological state.

General observation allows the veterinarian or technician to gauge the dog's demeanor, behavior, and any visible signs of discomfort or abnormalities. Weight assessment is also essential because it helps to identify any health issues related to body condition, such as obesity or underweight concerns, which can influence a dog's overall health status.

In contrast, a puppy training evaluation is focused on behavioral aspects and training progress rather than the physical health assessment that is the aim of a physical examination. Therefore, it is not considered a key component in this context.
