Animal portraits and Horsemanship

Una has been doing really well she is now going forward nicely and has started her canter work. I have had her out doing tilting a bit of dressage and  some hacking. She lacks confidence out on her own and can be a bit spooky so I am working on this with her by doing more groundwork as I know I have a hole there somewhere i need to fill in. She does have issues with horses galloping or cantering around her so I need her to become more comfortable with this as otherwise it means she gets worried everytime we are at a dressage test and the next arena has a canter class!
