Re: really REALLY nappy pony!
I think the most imprtant thing is to figure out whether she is nappign coz she is scared or nervous of something or whether she is just trying it on.
When Coco is scared of something he normally stiffens up and slows down, his head will get higher and higher, he is very focussed on a specific thing, he quivers his bottom lip (so sweet) and if he is petrified you can feel his whole body quivering and he will try and spin and run from the hideously scary scene! I normally let him stand and just look at what he is scared of. keep a contact so that he cant spin and run, but speak to him reassuringly and give him a rub/scratch on his withers. generally I feel him start to relax a bit, his head will start to lower and then I will ask him to take a step forward. As soon as he takes a step he gets loads of praise and reassurance and that is normally enough to convince him to give it a go and tip toe past but he will occassionally take a step, stop again, relax a bit, take another step, stop again, relax, step forwards again etc. I see it as my job to make him feel safe and convince him its not so scary and let him take the time to figure it out.
If it is stobborness I know when Coco is likely to do it, eg there are certain routes which if we turn one way we are going out for a longer ride, another way is a short route and sometimes he says 'No I'm going the short way!' I will now sponge the rein in the direction we are going to turn in advance of the turning so he knows where we are planning on going. I will put the schooling whip in the hand of the direction he would like to go and if he feels a bit resistant will tickle him on the botttom to remind him I have it there and I will use the leg on the side he will nap towards more strongly and tell him in a firm voice to walk on. Keep a good contact so that there is no chance of the head coming up, contact disappearing and enabling them to turn. If he starts slowing he gets a really big pony club kick and and tell him to walk on in a strong voice, if the kick doesn't work I will use the schooling whip to back up my leg aid. He does now go forwards and as soon as he does he gets praise for doing as I ask and the napping is very rare now, it used to be many times on every ride!
A few other little tips that used to work, if she turns to go the other way, keep turning her in tight little circles, go round and round and then when you are facing the way you want to go straighten up and give a big kick forwards. They will often take a step or two as they are either slightly confused as to the direction or just glad not to be doing tini tiny circles any more and once you have got them movintg they are easier to keep moving so then positive praise while kicking forwards. Another thing that worked, normally if Coco was scared, was reversing him past the sticky spot! Coco likes to reverse, ok we will reverse until we are past the point and then 'wow look we are past it, shall we try forwards again!' very occasionally I have had to get off but only if it is a scared nap and he is really too scared to do it on his own. We had this at the weekend for the 1st time in over a year as there was a dead badger on the side of the road with its head in the grass. Poor baby was quivering all over and I cant blame him coz he had no idea if the badger was wating to get him or what. There was no way he was going to relax and go past so I got off and walked in between him and the badger reassuring him the whole way. On the way back he was nervous but I didn't need to get off.
Good luck and keep at it, they all have to try their luck occasionally but you will get her through this!
