false pregnancy?

I was just reading up on false pregnancies in dogs and I really think that this the case with Lady. Apparently with false pregnancies dogs will get bigger in the mammary area and will go through all the same physical and psychological changes as if they really are pregnant. The milk eventually toward the end of the cycle will start to drain on it's own which is what is happening with Lady. My kids are sad that we probably won't be having any puppies but Brent and I are very relieved. I guess only time will tell if I'm correct.
