Great Dane Stud Dog

I am looking for either a Harlequin, Black, or Mantle Great Dane male to use as a stud for my female. Male MUST be in good health, have Vet records, AKC registered, and preferably have produced previous litters. My female is an AKC Great Dane, Mantle colored, has had 2 litters producing beautiful mantles, and is 25% European. We are located in New Jersey and willing to deal with people in our tri-state area. Frozen/Fresh semen is an option depending on pricing.
