Could you share a couple of pictures of her with us please? Take one full side shot down at her level, and one standing at her tail end looking forward down her sides, again down at her level.
Can't wait to see, and good idea regarding the ultrasound!
She may be having a false pregnancy. She really doesn't look 'developed' enough in her tummy to be at the stage of growing an udder. I think you will have to wait for the us to give you an answer.
I'm inclined to agree. I don't see any lopsided belly, and unless that little one is up by her spine and she's hiding it well, my guess would be that something else is causing the udder development. But, we're happy to watch and wait to hear what the ultrasound says! And I agree, she's a pretty girl!!
