Do you let your dog bark?

 I let my dogs bark I don't see a problem with it Copper barks all the time Daisy barks when she hears something outside and Lucky she rarely barks and when she does I know something is wrong, Princess barked at everything when she was out not all the time but if she saw someone she barked Copper is like Princess in that way but he hates my neighbor don't know why but if my dogs are out and the neighbors comes out Copper just barks at him and won't stop Daisy will bark when Copper does but then she'll stop, she used to be a big barker but guess in her old age she's calming down with that.

My father tries to get Copper to stop barking and I tell him leave the dog alone he's just warning you someone is out there, and I'm sorry if the neighbors don't like it there's a few things I don't like about what they do so, but no one has ever complained 

Copper will also bark at the neighbors behind us they don't have a fence and let their dogs run without a leash. The only time I hate the barking is when the dogs think no one is home and I'm in my room sleeping thats when Daisy barks alot because she hears things going on outside or if she see's cars pull up everytime it doesn't fail to have them bark when I'm trying to sleep

I think you should let you're dogs bark it's why they bark lol
