About Eden
Eden is an exceptional companion and protector for my family and farm. She finished her AKC championship around a year old and is full of joy and very loyal to her family. Eden is AKC and Sabbs appraised and registered, she is OFA cardiac, hips, elbows, and Wisdom dna tested. We have health testing data on several generations behind the puppies, many were/are very successful AKC show winners or Sabbs studbook appraised dogs. Eden is endlessly loving to her people and she enjoys the car, travel with her family, and is a big snuggler. She is protective of what she considers her people and animals. She is an incredible mother, constantly attending her pups and bringing all the toys in the house to their whelping box so they can snuggle with them. Eden adores toys and has had a stuffed pigeon and octopus since she was a young pup. Her loyalty and adoration can be seen in everything she does. Eden is a leader, but everything she does is in devotion to her people.
