Nine-axis inertial measurement unit output discriminates activities of varying intensity in the dog.

Objective: To explore relationships between 9-axis inertial measurement unit (IMU) output and activities of varying intensity in dogs of various sizes.

Animals: 20 healthy, agility course-trained dogs of various ages and sizes.

Procedures: Height, weight, body condition score, age, length from IMU to the ischium, and height of IMU to the floor were recorded.
