Kennel Diary, Loose Items: Dimensions of Dogs, 1890

The Breeding and Registration Records series is the strongest series in the collection as it contains many rare late-19th Century and early-20th Century materials on the breeding and care of Scottish Deerhounds.

The Breeder's Pedigree Book is of particular note. The book was a gift from the Duchess of Wellington given to George Sheperd Page when he purchased the Scottish Deerhound Bruar II. In edition to pedigrees of many of the dogs at Dunrobin Kennels, the book includes a variety of other materials related to the dogs including correspondence, clippings, and detailed notes. For example, Page's notes on Dunrobin remark that he was "A fine specimen of a deerhound, good disposition, and a grand sire; he would have been a dog of note had he not developed a weakness in his loins which came from a strain and ultimately cause his death" and the notes on Olga observe that she was "the finest deerhound bitch we have ever raised - She was a queen of her kind, standing over 30 inches at shoulders muscular and courageous yet to her friend she showed only the kindest and most obedient disposition. Her color was that rare silver grey, her eyes hazel and when she was excited how they sparkled. Her coat was long and fine with a slight wave but no trace of curl." Many small notes and clippings related to the dogs were interleaved among the pages and these documents have been retained in their own folders. The book works in conjunction with these documents to provide a picture of the breeding, care, look, and performance of the Dunrobin dogs.

The Kennel Diary includes the AKC Stud-Book registration slips for many of the Page's dogs, a ledger of breeding attempts and results, a ledger of pups, and a ledger of exhibitions and results. The back of the Kennel Diary includes a ledger of expenditures for the kennel which mostly consists of spendings on food but also includes expenses for other supplies and dog shows.

This series also includes pedigrees for the Scottish Deerhounds Olga and Bruar II expressed in the form of half-wheel genealogies.
