Quote #10
The Nogtail is exceptionally fast and difficult to catch, though if chased beyond the boundaries of a farm by a pure white dog, it will never return. The Department for the Regulation and Control of Magical Creatures (Pest Sub-Division) keeps a dozen albino bloodhounds for this purpose. (22.2)
We've never encountered a Nogtail (that we know of), but if we ever do, we'll know to call the Ministry of Magic right away thanks to the helpful information in Mr. Scamander's book. See? It's chock full of wisdom.
