Dog has engorged breasts and is still pregnant

Question
I have a pit bull that is pregnant and due at the end of the month.  I was taking her for her daily walk today and noticed that she has a breast that is really bigger than the others.  It is not hot or hard and when touched it not painful.  I was wondering if this was normal or not?  It is one of the first set of nipples starting at the rear.

Answer
Kayce-

Typically the rear two teets will have more milk then the rest of the teets. However, if it is much larger then any of the others and develops a hard, hot feel or seems painful, then there may be an infection and she needs a warm compress and a trip to the vet :) Without those symptoms however, I would just say that her milk is starting to come in a little unevenly, and you should be just fine.
