Dialectal or archaic form meaning to growl, snarl, or show teeth in a threatening manner, especially of an animal.
From Old English and Germanic roots related to guttural sounds, possibly connected to 'gear' or 'grate' in the sense of rough, harsh sounds.
Animal sound words vary wildly by dialect—what one region calls a 'geer' another calls a 'snarl,' and these distinctions were crucial before radio standardized how we describe animal behavior.
