Thank you Anna you have given me a lot to think about.
I did worry about whether or not to add the cross voice as it went against all of my training principles. When I was using it I would just greet her with 'dirty girl' in a growl tone, as opposed to 'clean' in a happy voice. I only tried negative reinforcement out just in case any 'positive' results occurred out of a result of her connecting her actions of being laid in it with an unhappy owner, and her not being laid in it with a happy owner. However I do hate doing it, as I have learnt that I can achieve so much more with my dogs by never telling them off (it sounds stupid but I see anything they do wrong as a result of me not training it right). Very shortly after I introduced this she would look very happy when I greeted her if she was clean, and she would avoid eye contact if she was laid in it, and her house training also seemed to click in place.
But I think your idea of just removing her sounds an even better one. I may just have to get her old crate out and stick it next to the new one (my bedroom is going to look like a prison with all these bars lol). This will stop her running around like the mad nutter she is when I am cleaning my carpet / her crate.
I will also change my approach to her at bath times. I tried to do it quietly without much interaction, because I was worried about reinforcing her being laid in it, by rewarding her with lots of rubs along her belly (as I wash her), and a happy voice. But I was also worried about making the bath a bad place, which is why I also try and connect it with positive experiences (e.g. treats as she is placed in). When I put her in with wee & poop on her she looks sad, but when she doesn't have it on she is as mad as she usually is.
However after reading your post I realise that maybe her 'emotions' are a result of how she feels about our interactions, and not the fact that she has been laid in her own stuff?
is she weeeing in one spot The problem appears to be accentuated in the area she sleeps. She rarely ever does anything and lay in it when she is beside me in the early - late afternoon & night time. Although if she was to have an accident when loose it tends to occur morning to late dinner time (a real wide stab in the dark is maybe this is the time that the last owner was at work?

). But she regally goes and does it and then lays in it if I am asleep (comfy bed loose on the bedroom floor, or the crate). She is fed in her crate, and I have tried placing her food bowl in the area beside her bed, but I think I understand why this does not happen. Before she got used to going outside if you did not watch her eat all of her food she would quite happily wee in the spot she was eating, and then go back to eating. After discovering this a couple of times I then had to resort to watching her from a distance to see if she put her bum downwards mid meal.
I know that not everyone agrees with their dogs being in the bedroom, but thats where she is. She isn't on the bed for two reasons, my partner is a turner in bed and I could see her being kicked off, and I think if I was to disturb her from her position she would just wee next to me. I was on the phone once, and she jumped up and weed within seconds, so I don't think that she perceives my bed as being sacred or anything lol.:rolleyes:
I think that maybe one of the things that I am feeling worried about is that I always thought that dogs were naturally clean (e.g. don't lay in their own stuff if they have a choice, and they don't do it in the area they eat). However she for a reason I can't guess at chooses to do this. I just feel if I could understand the reason then maybe I would have a better idea of a better solution. Hopefully time will resolve this ..... by the time it does though I think her showing days will be getting numbered as in our breed they tend to be shown young .... so it may be that she is just destined to be a pet (although sold as a show dog :-/ ).
I would love her to bits either way (we have both fallen head over heels in love with her), I just want to make her happy, and my rooms to stop smelling so strongly of disinfectant lol. :rolleyes:
By the way she is from the toy group, and the reason I have not identified her breed is because I am worried about someone reading this post, knowing who her last owner was, and then for them to start telling other people about how she came to me. I don't want to cause or be blamed for any negative feelings being directed towards them. However I feel so desperate for help that I just had to ask for it.
