Yes, many studies and applications have successfully employed Delsys EMG sensors and systems on animals. Be sure correctly identify appropriate muscle sites and remove all fur/hair prior to applying the sensors. Wipe the site carefully with isopropyl alcohol to remove all oils and dry dermis. Apply the sensor with the arrow on top parallel to the muscle fibers of interest, and use the Delsys Adhesive Interface to affix the sensor to the skin. In highly dynamic situation it may be necessary to wrap the EMG sensor with additional tape or elastic bandages.
