Terra is the most biddable, loving Collie with endless affection for all humans - but especially kids. She is smart as whip, super easy to train, and always looking to please. She has training in scent tracking, and has enjoyed every minute of it. Terra excels in obedience, scent work, and show good herding instincts. She is an absolutely wonderful mother, and a doting "aunt" to all of the puppies in our home.
