Odie Come training with service dog alert

Training Odie to come when he is called. Suddenly Charlie my diabetic alert dog made me aware of my sugar level. This was not planned but Odie actually alerted as well he just does not understand why yet. He is still in training. Charlie is 9 years old and has been fully trained to alert for 7 years. He has never failed me. Hopefully Odie follows in his footsteps.
