Barking

Wesha starts to bark more and more. She didn't bark at all in the beginning. But the last few days, she has started barking at people with dogs passing our garden, sometimes at kids running past or squeaking bicycles going past. She also barks when she hears another dog barking (which is kind of logical). Early this morning she barked at a man that was walking past our garden. He was only talking to someone he just met on the street!

This was all in the garden. But this morning, when she heard some noises in the kitchen, she even started to bark at that! Hmmmm... not really desirable. Now I am looking for hints and tips to keep her from barking.
