Monitoring the respiratory rate (RR) and heart rate (HR) of canines is of paramount importance for assessing their overall health and well-being. This study introduces a processing pipeline designed to accurately estimate dogs’ RR and HR using Frequency-Modulated Continuous Wave (FMCW) radar technology. Unlike previous work, we use a respiration harmonics removal step to enhance the estimated heart rates for dogs. An Inertial Measurement Unit (IMU)-based vital signs monitoring is then validated against reference instruments and used later as ground truth to evaluate the radar-based performance. Extensive experiments were conducted on a diverse set of dog subjects, which included a wide range of breeds, sizes, and ages, thereby ensuring the applicability of the findings across different dog populations. The outcomes of the study achieved an average error of 2.40 bpm for RR and 6.90 bpm for HR from 50cm distance. Furthermore, the research also yielded impressive results at an increased distance of 100 cm, with an average error of 2.58 bpm for RR and 7.70 bpm for HR. These findings underscore the potential of this contactless, radar-based approach to enhance the management of canine health and welfare.
