Chupacabras are mythical creatures and are not real. Their name comes from the Spanish language and directly translates to "goat sucker." The chupacabra is described as an upright, hairless creature the size of a small bear, and it is said to prey upon goats.
Many sightings of chupacabras in the United States are actually sightings of dogs or coyotes suffering from severe mange. Dogs or coyotes that are injured while attacking their prey may retreat without eating it. This leaves the dead or dying prey with characteristic marks on the neck from the canine teeth, as described in chupacabra folklore.
