We know the King of the Cats took an indirect role in events by saving Graymalk and Snuff via the Dog's Nest portal, and by imparting clues to the Closers' success. What's good for a feline semi-deity is good for a canine one as well, and Growler's own sympathies are likely with Snuff's faction, considering how the Dreamlands' wolf/dog paragon trains Snuff in stalking and combat. Openly telling Players what to do, at a level beyond "small wisdom", is probably pushing things too far - the animal-archetype figures can't take too active a part in the Game, even if the Players are of the species for which they are the sovereigns - so Growler doesn't dare antagonize the Great Old Ones by counseling Jack's companion any more than to say "Keep watching".
But Larry's wolf side is also within Growler's purview, as reigning paragon of dogs and wolves, so the Lord of the Canids spoke openly to Talbot's alter-ego when it was "sleeping" during the weeks without a full moon when Larry's body was in human form. Because Larry has little or no awareness of what his wolf experiences, when it's asleep/suppressed, the Wolf Man caught only the faintest impressions of what Growler had told his bestial side. Larry mistook these hints for a subconscious assessment of statistics, and Snuff called him an "intuitive calculator", but they were actually fed to Talbot by Growler, with the Wolf Man's wolf as intermediary.
This not only explains why Larry had such a knack for anticipating things, but also why he was ever-so-coincidentally able to hit upon the solution to maintaining his self-control under a full moon on the very night when that self-control would be necessary to save the world: like the King of the Cats, Growler passed on a last crucial hint to his waking-world agent, with the Great Old Ones none the wiser.
He'd have known more than enough about forensic osteometry to realize that the staked skeleton in the crypt wasn't Dracula, and he visits the Gipsy camp in his little-old-lady disguise almost immediately after word of the staking got out. One Sherlock Scan of the Gipsy wagons' visible contents and the depth of their wheels' ruts, and he'd have readily deduced where the Count's secret coffin was hidden, too.
