Dogs are cute, yes, but excessive crying is definitely not; hence, why it's absolutely necessary to stop your dog from crying.
It's either that, or you can cry along with him after you've been driven mad by all the ruckus.
There are many reasons why your dog cries, and finding out why is the first step to stop your dog from crying.
Here are some of the most common causes of incessant crying:

• He might be lonely or bored, especially if he's left alone in the house all day without a companion or toys while you're at work.
  
• He's under 3 years old, or is particularly active and has a lot of pent-up energy without outlets for it.
  
• He's afraid of loud noises.
  

Luckily, it's easier to stop your dog from crying when you know why he's crying.
This way you can approach the issue just as it needs to be addressed to successfully stop your dog from crying.
Here's how:

• Lonely dogs need attention, and you can stop your dog from crying by increasing his people time.
  Go on a class together, practice tricks and commands regularly, and just pet him, groom him, and play with him whenever you can.
  
• When you're out of the house, keep him busy with safe and interesting toys, as well as treats.
  You can also look into hiring a sitter or walker, or keeping him in a doggie day care center to stop your dog from crying.
  
• Active dogs need plenty of - you guessed it! - activity.
  To stop your dog from crying, you have to give him an outlet for his energy.
  Otherwise, this energy, when pent-up, builds up and leads to incessant crying.
  Make sure that he gets plenty of exercise.
  Walk him at least twice a day, and not just to go to the potty.
  Better yet, teach him to play fetch or Frisbee, and do it regularly to stop your dog from crying for good.
  
• For dogs who are sensitive to loud noises, proper desensitization is required to stop your dog from crying.
  It's best to consult a professional in this matter.
  You can, however, help you dog deal with the noise from thunderstorms and firecrackers by keeping him in a windowless room and putting on the TV or radio to mute outside noise.
  This should stop your dog from crying.
  

Indeed, the effort you put in to stop your dog from crying is effort well-spent.
Not only will you stop your dog from crying, you'll stop yourself - and your neighbors - from crying out of frustration, as well.
