Kate Winter teaches dog owners how to train their canine companions. During her spare time, accompanied by her Lab, Dakota, she explores the woods and beaches on foot or horseback.

She's dealt with her anger, depression, and blindness primarily on her own.

On a mission to find someone who will train a dog specifically for her, she ultimately zeroes in on Kate. They say lightning never strikes the same place twice.
