My Patterdale bitch had her first season/heat cycle about 2 months ago, everything went as normal (enlarged vulva, nipples etc) but her nipples still seem a bit swollen, especially the ones closest to her back end. Is this just her going through puberty & hormones settling down or could it be something else? She seems fine in herself, weight, appetite & really active, noticed she is trying to eat grass sometimes dont know weather this means anything, has been wormed etc. Any replies would be appreciated. Thanks, Rich
