I've got a Friesian that it 6 years old and is very nervous. When me and my mum first got her she was an angel and didn't do a thing wrong. Her previous owner said she had done some driving and riding before but we think it was more driving. Over the past few months she has become more and more nervous and seems to bolt at nearly everything, to the point where I feel very nervous to get back on her and my mum won't even try at the moment.
Is there anything anyone can suggest?
