First mistake, comparing dogs to kids.
Good/Great dogs breeds can be trained to a T, where kids and adults can deviate from their learned behavior and pick up new traits out of nowhere, we think for ourselves. Again, great breeds you should not have to worry about snapping when you don't give it something. The most you should be concerned with is your dog becoming antsy or restless, they'll get over it. Can't believe you made that comparison.

Yup, I made the comparison to illustrate a point. Don't pull it too thin.
Maintaining such an animal is not difficult. Let it be a part of the family. They need to feel like they belong. There is nothing wrong with that. If you can't provide that environment, buy a fish.
People leave these dogs chained up in the back yard, and only walk them for maintenance, or only let them in on occasion, and surround them with scolding the entire time.
A Pit Bull is a curious, intelligent, sociable animal by nature. They want to belong, and they need a bit of room to be themselves. If cared for properly, you'll end up with a great family pet. If cared for exceptionally, you'll end up with a four legged comedian that thinks it's a puppy at ten years of age.
Half the damned problem with dogs is all the training to create perfect behavior. They aren't machines.
The aforementioned Jesse is a prime example of someone encouraging and training polite and acceptable behavior, but allowing the damned thing to be a dog; and a happy one, at that.
This is perhaps the most misunderstood and yet still deadly breed one might encounter, and yet it's the most enthusiastic, polite, and entertaining dog I've ever known.
If you want a dog to snap, leave it alone too much, or train it too hard. Unfortunately, that's what people do with Pit Bulls that make the news.
