My dog barks constantly. It doesn't matter whether she's inside or outside, she barks. It's not an angry bark, it's a happy, playful kind of bark.

She barks at the most stupid things. She barks at our cat if it moves and the bird (in the cage) if it flaps its wings. She barks at the kids if they move. She barks when the phone rings and even if someone gets up off the couch. I've just put her outside because of her barking and she HAS NOT STOPPED all morning! I don't even know what she's barking at.

Please help me.
