Duke is a gorgeous black and white purebred Jack Russell terrier. He is small in statue and a wonderful representation of the breed. Duke is a very sweet, loving and calm Jack. Very tender hearted pup. Loves life and has a heart of gold! He has a nice pedigree. My daughter, who's dog this is, has to move and cannot have pets where she will be living, so much sacrifice this wonderful little guy! He has a lightly broken coat with black spots and a tri-colored face...he's awesome!
