Preston is a big sweet boy, over 100 lbs. He is about 4 years old. He is Anatolian Shepherd mixed with other things, maybe Pyrenees or big yellow Lab? He is friendly, quiet, and gentle. He is excited to explore the world and can climb out of a 6 foot kennel, so would need a very secure fenced yard. He seems ok with other dogs. We aren't sure if he is house trained but is fine in a crate. He walks well on a leash and doesn't tug. He's just a gentle and affectionate giant!
