I have finally come to the conclusion that my mare just doesn't like to go on a hack on her own. Whilst not dangerous, she is clearly stressed at being on her own and will snort, spook and power walk, even on a route that she has done many times before. However if I ride her with my daughter and her little cob, she is an angel, no snorting, no spooking and definitely no power walking, she is happy in front or behind him. Should I just accept that she is happier in company and not try to hack her on her own, or should I take her out now and then on her own, or should I try and always ride her on her own so she becomes used to that, then introduce the company? Any suggestions?
