Barking out of fear not aggression

[so5252]

I have a 1yr old Puggle that we got from the Pug Rescue about 6 months ago. We've been doing very well on the dog training but he ALWAYS barks at people when they come over to the house. He STILL barks at friends that we have over frequently (weekly or even every few days). The only time he will not bark at them is when they bring their dog along.

He is never agressive to people or dogs, and when he barks he runs away and has his tail down. This occurs at the house and on walks (not at the dog park). If the "humans" have dogs, he does not bark at them or run away.


Please help!!!

I have a similar problem. My six month old Shih-Poo puppy has just started barking when she sees herself in the windows at night or when someone comes to the door. Is this normal? She normally is not a barker and I don't want her to start barking whenever anyone comes to the door.
