All pet dogs detestation it when you leave them. Once they detect that you are about to go away, they make sure to let you understand it. The best way to defeat this sort of behavior is usually to mask it.
When you’re roaming about the home and your dog is fallowing you around, get your keys, make some noise with them. Get your jacket.
Do the things you usually would do when you are getting ready to leave.
By doing this, the dog will start associating those behaviors with normal time rather than associating them with you about to leave.
One more trick you can apply should be to pre-occupy your dog using a toy or treat. Give them whatever it is they love and they will be so preoccupied with it, they will not even notice you leaving.
What ever you need to do, don’t start discussion in unenthusiastic tones (like apologizing). This will likely only increase their anxiety levels, and thus make them bark even louder and longer.
