You can register the foal half arabian no matter if your mare is not pure bred or registered. The Arabian Horse Association allows registration of Purebred Arabians, Half Arabians (Really any percentage of Arabian blood, as long as one parent is a registered Purebred Arabian.) and Anglo Arabians.
That's one of the reasons I like the AHA so much. It offers an opportunity for foals that would not be registerable if they were another breed, to get papers.
She had a whole lot of sticky clear mucos today. She is really bouncing around in her udder area. She keeps looking at her back end and when she eats she will not rest long on her hind legs. She is right at 52 weeks today, I think going by what the vet thinks from palp last week. 342 days in foal again maybe.
These are from today, there is more bloody looking stuff around the outside ( I think you can tell from the picture the redness I am talking about), she would not let me open to look, kept moving when I tried to take a picture of her hind. I have to work 13 hour shifts the next two days..... So it will prob happen tonight GRRR!!
