Hello, I would love some opinions on something that is happening lately when walking my gelding pony, (by walking I mean in hand with his halter and lead not riding) I suspect it is since he is wanting to get as much grass as possible because he has very little this time of year, but he has been trying pull off the road toward the bit of grass coming out of the snow, but when I pull his head up since I want him focused on me and what I am working on him that day, he refuses to move. He stands still and won't walk.
What should I do at this time? He is usually a very respectful, he never kicks/bites, never refuses an obstacle (if I work him up to it obviously) in his agility, but what I am saying overall he is very willing.
I usually stand with him, not allowing him to eat, we just stand still until he decides he wants to continue. More times than not I will circle him and he will continue, but not always. What should I be doing to correct this?
Thanks in advance!
