Deer attacks on humans and pets have become so commonplace as to elicit many recent official warnings that people treat them like the dangerous wildlife that they are. There are not good statistics on the number of deer attacks because many are not reported.
Many people do not understand that deer are not like Bambi. Although deer generally are docile and timid animals that do not attack humans, the deer population explosion, due to human activity, has greatly increased deer-human contact. In addition deer have been forced to live in close proximity to humans and as a result they have lost their fear and become more aggressive toward humans, especially when feeling they or their young might be threatened.
With the ubiquity of phone cameras, the Internet abounds with disturbing video of deer violently attacking people and pets.
