Greyhounds recognize their owners. Greyhounds begin to have the ability to distinguish when they are two months old, and can remember the owner's voice, smell, behavioral habits, etc., and can recognize their owner in two or three months. The owner needs to interact with the dog. The greyhound will quickly recognize the owner after becoming familiar with the owner's smell and voice.
