Leitrim Boy was the second regimental pet. He was whelped on November 12th, 1907, bred by Mr. O'Malley, by Galtee Boy out of Carlow Norah. He was registered with the Kennel Club by his owner, Mr. T.J. Kilbride, with the incorrect information that his sire was Galtee and unregistered. In June, 1911 he was transferred from Mr. T.J. Kilbride to Mr. T. Kilbride and then in December, 1911 he was transferred from Mr. T. Kilbride to Lord Powerscourt. This may seem a little odd since he was presented to the Irish Guards by Lord Powerscourt in 1910, following his gaining of a second place in the Graduate Class and a third in the Limit Class at the Dublin Show in May that year.
