"She is nervous of large vehicles such as lorries, and will pull round a corner on her morning walk to get away from them. She can also be nervous of loud noises, for example if my fiancee accidentally drops something in the kitchen. But obviously none of these factors come into it. She is not remotely nervous of people, in fact quite the opposite. She is extremely friendly when she sees anybody and only ever guards on the property. We have tried really hard to pinpoint what could trigger this behaviour, however it literally could be any time of day/night, on lead or off (but mainly off), any wood/field. The only thing that seems to be constant is that it is only myself and my fiancee around when she does it, as if there are other dogs/people about, she is more interested in them. " After re-reading your posts YES Find a Private trainer that has experience with Neo or at least molossers( Rottweiler background would work). I'm not one to promote the Heavy Handed Kohler type training HOWEVER, this pup needs at least to corrected (at least once) in Biblical fashion :lol: At 8wks this is realitively easy....at 8 months only the experienced should concider this option. On the positive side everything you describe can be corrected with work & comittment. I thik your going to find that as Gary eluded to your're going to have to re-think how you "own" your dog. The private trainer will help with that. [color=red]WELCOME TO THE BOARD[/color] I'd encourage to to read through the forums.
