Background: I have a hackney pony, 13.3hands tall named Stormy and getting to be a chunker! I just graduated college, work full time, just got married, bought my first house, and haven't had a lot of time to work him.
Anyways, When I get a chance I like to lunge him, he is getting barn sour and I'm working him at the barn to maybe get him to not like it and I don't think it's working. When lunging him though, I have him in a 15ft circle with the lunge line and if I go any faster than a slow trot he slips and falls in the circle. He seems to be leaning into the circle way too much and he slips on the dirt, even in the driest position. I tried making a bigger circle but his lunging skills are rusty and then he is more likely to stop, spin in the other direction and all the issues start. I want to work him in close then push him out farther but right now anything past 15ft and he loses focus. Am I making the circle too small? Or is he having an issue on his end? Just wanting to mill it over with everyone because I'm apprehensive on working him because I don't want him hurt.
