Positive Dog Training at a Healthy Pace
If they whine or cry when left in the confinement area alone, either the training began before they fully associated it with positive things, or you have left them alone for too long. Don't immediately let them out because they'll learn that the whining gets them out and earns attention. Return to showing them the safe space can be a happy place, and once you're ready to train again shorten the time and then build it a little more slowly.
Once they have learned to be confident and calm on their own and have mastered potty training and good behavior, you can move away from the specific confinement area and into leaving them at home alone one room at a time. Eventually, you want to be able to trust your dog with more freedom, knowing he or she will remain calm and self-assured.
This process can take a while at the beginning, and if you don't have the time to be home with them you can find a trusted dog sitter or hire a professional trainer and they can also work on potty training at the same time. When your puppy has worked up to being alone for half of the day but not the full time you're away, a dog walker is also a great solution to give them companionship and attention when needed.
