The respiratory rate is the vital sign that indicates how well an animal is breathing. It measures the number of breaths taken per minute and reflects the efficiency of the respiratory system in delivering oxygen to the body and removing carbon dioxide. A normal respiratory rate indicates that the animal is likely breathing adequately, while an abnormal rate—whether it is too fast (tachypnea) or too slow (bradypnea)—can indicate respiratory distress or underlying health issues.

In evaluating an animal's overall health, the respiratory rate is essential for assessing respiratory function, especially in cases of illness or injury. Factors such as age, species, and activity level can influence what is considered a normal respiratory rate, but consistent monitoring can help veterinary professionals detect changes that may require further investigation.

Other vital signs, such as heart rate and blood pressure, are important for evaluating cardiac function and circulatory health, while body temperature provides insight into metabolic and infectious conditions. However, these parameters do not directly assess respiratory efficiency in the same way that respiratory rate does.
