Does the dog ever no-go on you in a test? Maybe you got a Rodman dog (doesn't like to train, but likes to play the game ). I got a girl does the same thing in training to me; I know she's gonna no-go, it's just going to happen and I just got to deal with-it. I either step her offline (wait to run her), hoping she'll stop her game (doesn't happen often but we can hope ). Or No-nonsense, bump her forward (I don't use the sit, (as soon as I see the change) I just walk-off-heel-(nick), pay-attention mark), seems if you do the sit they anticipate the nick,(it becomes a custom just what they do before they run) and you end-up playing their game. Sometimes I'll also do a collar-ear shake, No pay-attention. Different forms of correction/pressure. We mix it up, trying to break the custom.
I've come to the conclusion, it's just something with her and me, she doesn't pull this crap with others. I think because the others, took care of it right away, (it never became a custom). But her and I have history, a history where she knows she can play with me, so I got to be tough (but fair)every-time. Hope that perhaps one day it'll connect that I no longer play her game, and she'll stop playing it (hasn't happened yet but I'm getting more consistent). Plus side she's never ever done it to me in a test, she loves tests. She also doesn't do it to me if we train alone. But get her in a training group (club days especially), bingo back into the custom. The more people the worst she is, she loves to play to a crowd. Thus I've become very particular in where I train her, I train with a group that knows the dog, and how she trains, so we no longer get audience interference "Poor dog/too much pressure, bad-mean trainer" (Try as I might even when I absolutely know I'm being fair the audience affects me, the dog can read it and we back slide, so no-more of that).
Just keeping telling your-self; I don't need to look good, I don't need to win training day,, I just need to train (that means the dog gives effort and does as he's told), If I can maintain the No-nonsense approach we get a lot of work done in every training session. Sure we look terrible, but we're getting things done. Negative sometimes it's very tiring for the trainer, however When Dennis Rodman shows up on test day, it's worth it .
Favorite quote from a Club training day in all seriousness stated to me after running my MHR, HRCH, MH " When did you get a Junior Dog?"
If you ever figure-out the secret on how to get a Rodman to love training, please let me know
