i have bought the dr.cooks bitless bridle but i am having a few problems. i find it really hard to get my mare to stop in it i have 2 pull harder than i like to and she does not respond straight away. she is very forward going anyway but i find she is a bit like 'freedom' and just takes off. is there anything im doing wrong? i have it sitting right. any tips on how i can get her to respond i dont want 2 go back to bits but i dont think i have a choice. any advice thanks
