Great Dane
Genomic analysis indicates that although there has been some DNA sharing between the Irish wolfhound with the Deerhound, Whippet, and Greyhound, there has been significant sharing of DNA between the Irish Wolfhound with the Great Dane. One writer has stated that for the Irish Wolfhound, "the Great Dane appearance is strongly marked too prominently before the 20th Century". George Augustus Graham created the modern Irish wolfhound breed that retained the appearance of the original form but not its genetic ancestry.
