I just purchased a female red brindle who's grandfather is CH Leatherneck Ishanas Shadoboxer. Her father is International/American Champion Simba VIII. I waited 6 months to get a puppy from Simba VIII because of his bloodline. My female Black Oaks Mystic Journey (Sasha) is awesome because of her bloodline. The Leatherneck influence is on her father's side of the pedigree and he has 5 generations of champions in his pedigree.
