When they are pregnant, they feel full all the time, and I think the have to urinate more frequently. Every hour though is a little too frequent. I wonder if she has a bladder infection. It is possible. But be careful if you have to give her antibiotics. I think amoxicillin and carprofin is ok for pregnant or lactating females, but I can't be 100% sure. If you take her in, just make sure you mention that she has puppies and they are still eating some from her.
BB and Wilderness are a higher quality food. I prefer to wean pups on a food that is easy for the buyers to get, but still has good ingredients. The higher quality foods have more calories so you feed even less of them. Usually the bag over-estimates how much you should feed, so you have to be careful. Again, loose stool can be a symptom of over-eating.
