Specially trained Karelian Bear Dogs are used in combination with aversive conditioning tools and structured learning situations to teach bears to recognize and avoid human territory. Carrie Hunt's Bear Shepherding techniques are an innovative combination of animal-to-animal communication using Bear Dogs and human-to-bear communication. Using her knowledge of bear behavior, Hunt structures learning experiences that a bear can absorb and retain.
