I have two puppies. A girl named Cookie who is 4 months old and a boy named Rocky who is 3 months. I read an article about using a confinement space for indoor potty training. Following the article's directions, I set up a confinement area by using an exercise pen and putting in a bed with toys, food and water bowls, and potty pads. This particular article said to make sure there is no uncovered floor space, but I do have each area distinctly arranged. Per advice from other sources, I also take the puppies to this area by following a feeding, playing, and sleeping schedule. When I take them to the pen, they don't go potty. For example, I just took them to the pen after 2 hours of napping. I put food in their bowls and made sure they finished eating. It has been over an hour and they have not gone. There have been times I let them out, thinking they just didn't need to go and within 5 minutes, they have eliminated somewhere else in the house. What do I do at this point?
