I could use some advice. I am a first time horse owner who has thus far had no issue leading my horse across his large paddock to the gate for our rides (I switch it up so we do a variety of arena work and hacking). The last two times I have led him, he has gone a few feet and then stopped. I think he might be reluctant to leave the herd and hay (the rest of his buddies are happily chomping away together). I apply pressure to the lead and release when he walks forward - a few more feet - before we repeat this process again. I've even given him a light flick with the end of the lead when pressure doesn't help, but I'm not sure if I'm waiting long enough or if this is the right move. Once we are halfway through the field he begins walking nicely again.
Can anyone offer me guidance? Ideally, I would love to return to him coming to the gate as he often started doing at the farm we were at before of his own accord. Any tips?
