Why are my 27-day-old puppies crying when I move them from their box?

Puppies cry when they want something like to eat or attention, or possibly to go outside. They are a little young to know how to be properly potty trained. I would make sure the mom is nursing then properly and everyone is properly gaining weight. I would make sure there isn't another reason they could be crying. With them being so young, I would be careful letting them spend too much time in the environment because they are at high risk for different illnesses since their immune system is weak and they haven't had their shots. I hope this helps. If it doesn't directly answer what you need to know, please write back with a more specific question. Thank you!
