newborn and dog-- bark collar??

Kay

we have a baby coming very soon and im very anxious about how one of my dogs will behave especially with the baby. she's some type of jack russell mix and she barks and does this horrible howl that gives me alot of anxiety. no matter what me and my partner do, we cant prevent her from barking and its to the point where we cant have company over because she barks as if someone is cutting her head off. we've talked about getting a bark collar.. i looked on amazon and there is one that has a beep, vibrate and shock option and i just want to be able to snap my dog out of her barking and howls and gain control of my life again.
