Besides the dog's own disposition, there is the problem of whether the dog and the prospective owner will make a good match. For example, if you give a lively and active dog to a quiet homebody girl, it could be torture for both the person and the dog.
除了狗的特性外，也要看是否能與領養人「速配」，像是活潑好動的狗，若給了居家型的文靜女生，可能對人和狗都會是一場折磨。
