Hi Caron,
I find that my girls often get enlarged glands in their mammaries, when having phantom pregnacies. They feel like hard beads, are not sore or bothering the bitch in any way. They shrink away when their hormones are back to normal. Having said this, I still think the best thing to do, is having her checked by the vet, just to make sure.
I wouldn't worry too much about it, though.
Good luck to you and Mindy,
Karen :p
