Would you have any advice please. Have brought a 3rd year old gelding to professional trainer to be broken and riding. Overall reports that he has a great step, big powerful horse, very good over pole but is very childish for his age. One day will ride ok but next easily distracted won't move also has a habit of biting. Has been with the trainer 7 weeks recommends we take him back let him out in paddock for a couple of months to see if he matures. Then bring him back for further two weeks during summer. Would really like to hear others opinions.
