So I went to look at a mare I'm thinking about buying for trails and pasture riding. I liked pretty much everything about her except that she cribs (corrected with a collar) and has a bump on her back (and of course she's mareish). Now she's a long horse and was used as a broodmare. She's not swaybacked. The guy who owns her is a friend and said he had a chiro look at her and he said it didnt bother her. I poked and prodded and pinched all over her back an she had the same reaction on that spot as the rest of her back. It didnt seem to cause her pain. He has been riding her and said he hasnt had problems. I have not gotten to ride her b/c of the rain. So I do not know how she does during a workout. Any ideas? The bump is located in the lumbar region and I'm thinking it might be a hunter's bump. Does anyone have any details?
P.S. She's 12.
