In her two years of training, the young dog never had to retrieve anything that heavy, so she was reluctant with the weight in her mouth. I healed her, placed the base of the goose's neck near her mouth, and told her to fetch and hold. Her head sank with the 15-pound bird hanging below. By holding the bird, she began to understand the weight and use more pressure to carry it. As Boise continued to hold, I began walking away and made her heal at my side, all the while carrying the goose.
