A dialysis device 1 includes a water supply passage 15 for supplying clean water to solution supply chambers 35a and 35b, and a waste solution passage for discharging a used dialysis solution from solution collection chambers 34a and 34b, and the water supply passage includes a concentrate solution pump 21 that supplies a dialysis concentrate solution from concentrate solution supply source 19. The current signal is sampled to form current sample values, and a current measurement variable is determined. One or more stimulation electrodes are adapted to interface with tissue of the horse for delivering the treatment signal to continuously or intermittently stimulate soft palate tissue of the horse during an entire period of increased activity of the horse or for training prior to exercise.
