I am sort of breaking this hackney into been rode, she has been rode before and she used to pull the cart at the 5 mile (a gypsy thing for making their horses trot for 5 miles non stop). Since my yard owner bought her due to her been un-nourished, she is well now and we have had the vet to her and then the vet said she could begin to be rode again. So we tacked her up and lunged her and sat 2 sacks of potatoes on her back and led and lunged her around, she was great. But then when I hopped on her back and I walked her around, she was great walking around and within the next month of me walking her around I went to trot her and she keeps prancing and messing about. I have even began to lunge her for half an hour before riding her and she is still prancing around. I still ride her though but I just ride her out in walk (bit boring,lol). Just thought you could give me some advice.
