Opinions wanted please.
I have a very sensitive springer spaniel.
After working on the pheasant last season he was as bold as brass and won at his first working test in March without having seen a canvas dummy since the previous September.
He has done well this summer and has qualified for the World Series Finals this coming weekend. I have qualified for the finals before and I know that the tests involved are not really suited to him, so I have upped his training to work on some of his 'weaknesses'.
Anyway, I have managed to find a field to use which is mown, perfectly flat, square and fenced; almost identical to the ground at the finals. So I took him there on Thursday and, to put it politely, he was rubbish. He looked at me as though I was speaking Japanese and had never done any training with him before. He is very easily upset so I gave him a couple of really easy things to do to end on a high and then left him all weekend (no, I didn't leave him in the field, I mean I didn't do any training with him all weekend

). Took him back to the field again last night and, same again, rubbish. I'm not asking him to do anything he does not usually do really well, but he is either ignoring me or is genuinely confused
So, my dilemma is, do I
1) keep on with him, with the risk of him shutting down
2) take him back to train in areas he is happy with, but are nothing like the set up he will be faced with on Sunday
3) stop all training and just see what happens on the day?
I love this little chap ever so much and will still love him to bits if we are rubbish on Sunday, but there is a £20k prize at stake so I'd kinda like to give us the best chance!!
