Hi i was just wondering if anyone out there can give me some advice. Ive just taken on this 15.3hh welsh section d. he is a lovely cheeky chap but when i am lungeing he gets to cheeky. He will lunge on the left rain perfectly but as soon as i change his rein he turns in and changes back to the left rein. I have tried someone lunging me on him, i have tried lungeing with someone leading but he barges them out the way, i have had the back specialist to him (nothing), i've lunged in a bridle and many more but still he does it. HELP!!!!
