Oh my gosh! Did your vet say that Sugar's tummy is normal? I don't think I've ever seen a pregnant mare's belly like that.
No, he didnt say it was normal, he felt it and said it was fluid. This is why I have been describing it as a "tire"!
He said it should go down after she foals.
Sorry about the state of her, she was brushed and all nice and then decided to roll and plait her mane! : )
