"It’s good to know that Melville, according to Nathaniel Hawthorne’s son, Julian, had the company of 'a black Newfoundland dog, shaggy like himself, good natured and simple.'"

"('My shaggy ally' was how [Emily] Dickinson referred to her own Newfie, Carlo.) Readers of Moby-Dick may remember that after Ishmael wakes up in Queequeg’s arms in the Spouter-Inn, and complains of the 'unbecomingness of his hugging a fellow male in that matrimonial sort of style,' Queequeg 'shook himself all over like a Newfoundland dog just from the water.'"

 
Writes Christopher Benfey in   "Shaggy Allies/It’s comforting to know that Melville, isolated in an old farmhouse in Pittsfield, had the company of a dog" (NYRB).

I looked up the passage in my own (Kindle) copy of the book:

Throwing aside the counterpane, there lay the tomahawk sleeping by the savage's side, as if it were a hatchet-faced baby. A pretty pickle, truly, thought I; abed here in a strange house in the broad day, with a cannibal and a tomahawk! "Queequeg!—in the name of goodness, Queequeg, wake!" At length, by dint of much wriggling, and loud and incessant expostulations upon the unbecomingness of his hugging a fellow male in that matrimonial sort of style, I succeeded in extracting a grunt; and presently, he drew back his arm, shook himself all over like a Newfoundland dog just from the water, and sat up in bed, stiff as a pike-staff, looking at me, and rubbing his eyes as if he did not altogether remember how I came to be there, though a dim consciousness of knowing something about me seemed slowly dawning over him. Meanwhile, I lay quietly eyeing him, having no serious misgivings now, and bent upon narrowly observing so curious a creature. When, at last, his mind seemed made up touching the character of his bedfellow, and he became, as it were, reconciled to the fact; he jumped out upon the floor, and by certain signs and sounds gave me to understand that, if it pleased me, he would dress first and then leave me to dress afterwards, leaving the whole apartment to myself. Thinks I, Queequeg, under the circumstances, this is a very civilized overture; but, the truth is, these savages have an innate sense of delicacy, say what you will; it is marvellous how essentially polite they are. I pay this particular compliment to Queequeg, because he treated me with so much civility and consideration, while I was guilty of great rudeness; staring at him from the bed, and watching all his toilette motions; for the time my curiosity getting the better of my breeding. Nevertheless, a man like Queequeg you don't see every day, he and his ways were well worth unusual regarding....
