This behavior is not intended to be a retaliatory response, but a panic response to frightening situations (from the dogs' point of view).
At this point, you should consult a separation anxiety dog trainer. You can easily appoint them by visiting separationanxietysorted.com. The dog trainer will help your dog to get out from separation anxiety problems.
