Deer are often seen in suburban and rural areas, leading many to wonder about their potential as companion animals. While some deer may become accustomed to human presence, they cannot be truly tamed or domesticated like common pets. Their inherent biological and behavioral traits prevent them from becoming suitable domestic animals, and attempting such a relationship carries significant risks for both humans and the deer.
Understanding Taming and Domestication
Understanding the distinction between taming and domestication is key to comprehending why deer remain wild animals. Taming refers to the behavioral modification of an individual wild-born animal, where its natural avoidance of humans is reduced, and it learns to tolerate human presence. This learned behavior does not alter its genetic makeup or wild instincts. A hand-raised cheetah, for instance, can be tamed, but its species is not domesticated.
Domestication, conversely, is a multi-generational process involving permanent genetic modification of a species through selective breeding. This process results in an inherited predisposition toward humans, leading to physical and behavioral changes like increased docility and altered reproductive cycles. Domestication typically requires over 10 generations of human-controlled breeding, permanently altering the animal’s DNA. While deer can be tamed to some extent, they have not undergone this genetic alteration, meaning their inherent wildness persists.
Why Deer Remain Wild Animals
Deer possess biological and behavioral characteristics that fundamentally oppose domestication. A primary factor is their strong innate flight response, causing them to flee from perceived threats, including humans. This deep-seated wariness makes consistent human interaction challenging and stressful. Even deer raised by humans often revert to wild behaviors as they mature, becoming unpredictable or aggressive, particularly during breeding seasons.
Their dietary needs also contribute to their wild nature. Deer are selective foragers, requiring a varied diet of natural vegetation difficult to replicate in captivity. Unlike domesticated livestock, deer struggle to thrive on human-provided food, which can lead to health issues. Furthermore, their social structures and tendencies to panic and injure themselves in enclosed spaces make them unsuitable for traditional farming or pet keeping.
Dangers of Attempting to Tame Deer
Attempting to tame or keep deer poses substantial dangers to both animals and humans. For humans, there is a serious risk of injury from unpredictable aggression, especially from adult bucks during the rut (mating season), which can involve kicking, goring with antlers, or charging. Even does with fawns can become aggressive if they perceive a threat to their young. Since 1988, at least 74 incidents of captive or free-ranging deer attacking people in the United States have resulted in injuries and fatalities.
For the deer, human care can lead to improper diets, health problems, and hindered natural foraging skills. Habituation to humans increases their vulnerability to vehicles and other dangers if they wander into human-populated areas. Legally, keeping wild deer as pets is prohibited in most U.S. states without specific permits, which are often difficult to obtain. Illegally held deer may be confiscated and humanely euthanized due to concerns about disease transmission and public safety.
How to Coexist Safely with Wild Deer
Coexisting safely with wild deer involves respecting their natural behaviors and maintaining a respectful distance. Never feed wild deer, as this leads to habituation, causing them to lose their natural fear of humans and increasing their reliance on nutritionally inadequate human-provided food. Such habituation can draw deer into residential areas, increasing the risk of vehicle collisions and potential disease transmission.
When encountering a deer, remain calm and give the animal ample space, ideally at least 50 meters. Avoid sudden movements or direct eye contact, as these can be interpreted as aggressive gestures. If a deer approaches, slowly back away while facing it, creating distance without turning your back. To protect property, use deer-resistant plants like boxwood, catmint, lavender, or yarrow, which deer avoid due to their texture, scent, or toxicity. For injured or distressed deer, contact local wildlife authorities or licensed rehabilitators rather than attempting to intervene yourself.
