[ "Dinks," Mayhew, and Hutchinson/ The Dog ]
This work is little more than a combination of three previous works: The Sportsman's Vade Mecum by "Dinks" along with Edward Mayhew's Dogs and Their Management, and Col. W. N. Hutchinson's Dog Breaking, all of it edited, abridged, and compiled by "Frank Forester," the pseudonym used by the English novelist, translator, and sporting writer Henry William Herbert (who spent much of his later adult life in America).
This book was first published in 1857 (Stringer and Townsend: New York), the year before Herbert's suicide, and was republished multiple times through the early 1870s.
Newfoundlands are mentioned nearly a dozen times in this work, but other than the one reference in The Sportsman's Vade Mecum (itself an almost incidental reference to a Newf cross), all the mentions are from Mayhew's volume, and those are only general comments indicating their large size (and how that size requires larger doses of medicine, primarily); there is no discussion of appearance, temperament, behavior, trainability, etc. As "Forester" notes in his preface to this 'combined' volume, he removed much of the anecdotal material in Hutchinson's Dog Breaking, which in this volume contains no mentions of Newfoundlands at all.
