Is it possible you could be feeding and giving water too often/ Or feeding and giving water at random times? they need a consistant schedule so you can learn when they need to go potty. Also make sure you never let them out unleashed until they are COMPLETELY trained to come to you. They can dart around sooo fast that you would be helpless if they go in front of a car. Victoria Stilwell is awesome and so is Cesar Millan aka the Dog Whisperer. Good luck with the training and please keep us updated on your progress.
Blessings to you
