Shock Collar For Dogs Barking

How I can stop barking nuisance?
My 9 month old puppy Zoe barks for no apparent reason. This morning at 6:30 in the morning began barking. I looked out the window and saw nothing. She has 3 offspring or relatives to play with other villains, Riley, and Bailey, so I know you're not alone. She is very friendly and tries to jump on me when I go to play with her and feeding her. Sometimes it starts at night with the barking annoying and I have fear of the neighbors will call the Parkinson's disease. I was told to try a collar that emits a sound that dogs can not stand that sound every time the dog barks or a shock collar. I never wear a collar shock, but what about the necklace that makes a noise when they bark? Oh, my puppies are Shih-tzu and Lhasa Apso mix
Get A muzzle …. My dog ran 4 ….
