[ The Dog Fancier ]
This American magazine (Battle Creek, MI) began publication in 1891.
The October, 1904, issue carried this brief note, interesting for its remark on the waning, or once-waning, popularity of the Newfoundland breed, a phenomenon noted by other dog fanciers at the time. See also this article from the November, 1917, issue of this same magazine.
That much neglected breed, the Newfoundland, which still has many admirers in this country, is becoming quite popular in Maine. Several of the fanciers in the vicinity of Bangor have been breeding and making a specialty of the Newfoundland, and F. J. Martin, the Mastiff fancier, has imported two or three Newfoundland youngsters. (6)
The idea that the Newfoundland was a vanishing breed was touched on in a surprising number of magazine articles and books in the early years of the 20th Century. For discussion of the idea, see this article here at The Cultured Newf.
