How to stop my dog barking at everything?

[luckymama]

I have a chihuahua who is 2, she barks at absolutely everything. No-one can come to the door without her barking her head off. How do i stop her?
My other dog will stop barking when i tell him to.

water spray bottle?

it worked when our puppy was scratching at shut doors. he was scratching the paint off the doors and stopped when we squirted him.

it hasnt put him off water any he still loves a bath, the pool and beach.
