"...and one of them had the cheek to call me a mangy old goat! I should've hauled her off to detention. The utter nerve! There's no mange on me!"
Argus Filch[src]

Mange is a class of contagious skin diseases of mammals caused by parasitic mites, which includes scabies and demodicosis.

Sometime in the 1991-1992 school year, someone called Argus Filch, the caretaker at Hogwarts School of Witchcraft and Wizardry, a "mangy old goat". Filch took offence to that, particularly because of the fact he had no mange on him.[1]
