A Woman-Owned Ranch Built for Happy, Healthy Dogs Our Story VIEW STAFF Jumping Jack Dog Ranch would not have been created if it weren't for a special black lab named Jack Mooper who changed the course of my life. On my 20th birthday, my parents gave me the best birthday gift ever – Jack. He was a tiny, energetic, and rambunctious black lab puppy, and I had no idea what kind of a ride he would take me on.
