If she's so lazy why is she "flying to the other end of the field"? That to me doesn't sound like a lazy horse at all, but a horse with lack of respect. Period. Lol, I'm sorry but I really had to laugh at your response.
Lack of respect for what? It's a live creature with free legs in own field. My paint (lowest in pecking order) run away from my qh on daily basis for fun. So is THAT disrespect towards the alpha mare as well? Do I have to take my big carrot stick, go, smack her butt and chase her down back to the barn? Or catch her and move her hindquarters till she drops dead, so she's be "restpectful" for me?
I don't see any lack of respect when I trim/brush/clip/vacuum/giving dewormer (all halter-free), riding, lunging, or work on ground. Or when she's (being a very strong alpha mare) is politely waiting for the paint to finish her food even though she's dying to chase her away and finish it up, but she knows it's a big "no-no" (while I'm around). I think I'll rather live with the fact of me going down the field where she's politely waiting for me to put a halter on (while she could of just keep running away from all around the field), then use the grain or treats as a bribary to catch the horse. If she's lazy and try to avoid work or just do it for fun I do NOT see it as a disrespect.
