My girl does most of the above listed things except that she does neck grab other dogs, but when she once caught and killed a squirrel, she grabbed and shook it, killing it immediately. Thereafter she was not at all interested in the prey and walked off. Another dog, a labradoodle, went over to grab the squirrel and started playing all over the field with it till its owner got it away from him. Shaye had no interest at all in this exchange because she did what she set out to do - catch and kill.
