I went over to look at the mare and she was a stocky bay that appeared to be around 6 or 7. My friend didn't know much about her, and her owner wasn't there. I went out in the pasture to see if I could catch her and when I got close to her, she pinned her ears back, squealed, turned and ran. As she was running off, I could see something shaking between her legs and I thought "This is a GELDING!" but nope - it was two MASSIVE udders. They were very swollen and full. Yet, she didn't look to be pregnant...? She was somewhat ribby (typical tb) and was not wider at the flanks (or anywhere else). I asked my friend and she said "Yeah, they tried to breed her. That's why they're giving her away, because they want someone to breed her." I was confused.
Sorry for the long story, but here's the question: Can unbred mares get huge swollen teats like that? This mare's body condition doesn't make her appear bred, and yet her teats are the size of a mare's that is ready to foal. She is RIGHT off the track, which would leave no time for a breeding nearly a year ago... right?
