So when I bought my horse I was told she was a TB but do you guys think she is pure TB or could there be something else in her. She is a very quiet horse on the ground and most times when ridden apart from an odd buck. When I first got her and was trying her out in cantering she took off like really fast when making the transition. I dunno if that was just on her or she didn't know what to do. Now she does it fine. She holds her tail up when she is ridden. Umm I dunno what else to add but if you have questions just ask.
