Can a golden retriever kill a person?

A golden retriever can kill a young deer, but not an adult deer, unless it's an adept hunter that has learned to hunt and kill deer for food (which is probable, especially if forced to survive in the wild). Adult deer have sharp hooves that can slash a dog pretty badly if it gets too close. Rutting bucks have sharp points on their antlers that can prove fatal to a dog if the points happened to gore the dog.
