[ London Times ]
This newspaper, most correctly known simply as The Times, began publication in 1785 and continues to this day.
The edition of November 12, 1845, carried the following "Newf for sale" notice. No mention of coat color but interesting for what it does identify as the dog's important qualities.
NEWFOUNDLAND DOG. — To be SOLD, a thoroughbred NEWFOUNDLAND DOG, one of the finest in the kingdom, about two years old, very sagacious, extremely powerful, and a first-rate water dog. To be seen at Gibb's livery stables, Jewry-street, Aldgate.
