Ground manners: leading and hosing off legs?

Lilly has always had issues with being pushy and having a lack of manners but she's really bad with leading in from the feild. She pulls me like crazy, yesterday I was leading her in and she snatched the rope out of my hands and just bolted off with the other horses around her galloping and bucking with her. I have a pressure headcollar which helps but she still pulls, tucks her head and prances around. The other issue is that there's a lot of mud and it's been raining nearly nonstop for nearly 2 weeks, somehow she manages to get mud all up her legs and her belly. Her legs have to be hosed off every night when she comes in, thing is that she won't stand still, she spins round where she's tied even if your stood in the way. She just doesn't care. All of the other horses stand and don't even have to be tied but she has to be tied and held and even then she carries on. It's super embarring having the only horse that won't stand completely still. She just lacks respect to be honest, I've had her for 8 months, she came from a dealer, she's 6 so still a baby but those are no excuse for her behaving like she is. She's nearly knocked me over, stood on me and she's made me pull muscles in my arms and back because she just pulls constantly. To hose her feet off it takes about 10 sometimes 15 minutes, it's ridiculous. She's an angel to ride, very rare for her to misbehave now but on the ground either just normal leading and things or lunging she just doesn't care and just has no respect. Help? I can't ask my trainer since she's in the middle of race season. She never liked her feet or head being touched before but she's fine with it now, it's just leading and hosing really.
