I'm glad I popped in.....
I have been having very similar problems to the ones reported in this thread and the one linked to also.
Dog is happy go lucky at any other time, very social and stable, good with kids, ignores other dogs for the most part and plays with me always, ignoring anyone else who is around.
If I tell her to "go see em" that means she can go to be petted and this is normally reserved for family members, but may also include people I know. The dog will go, tail wagging and get petted then come back to me for play.
Now to the problem.......
When I put her in her crate in the car and close or lock the door she goes absolutely NUTS, very aggressive, territorial, almost in defense (maybe actually in defence but I can't read it properly).
When I open the crate door again I have a different dog who can be petted as long as the door is left open and she has her head out. If I put my hand in while she is fully inside the crate and posturing up I WILL get bitten (and I have been, but not broken skin, just a warning shot). The dog is a decent Schutzhund dog and if she wanted to do damage she would have.
This only happens when I close or lock the door when I'm about to go, if I approach the crate on my return to let the dog out there is "normally" no issue. It's as if the dog has an objection to being locked up or left? But she does happily go into the crate on most occasions.
She is quite a dominant bitch, quite hard also and this is where the problem is. Nothing I do to correct her for this (including remote collar) has done anything to fix this behaviour.
Things I've tried:
I've tried the dominant dog collar, dragging her out and performing an alfa roll (not recommended unless you are quite strong), no bark collar on various settings and remote trainer on various settings, which the dog just fights through.
Mistakes I've made that I know about:
Put dog in crate when young with toys, then taking toys away.
Put dog in crate with food/bone/pigs ear and messing about at rear of car doing something else (thus I assume making the dog uneasy about my presence).
Making too big a deal of the issue losing temper/shouting etc. (not really a good idea as it solves nothing). I'd include corrections in this as well as my current train of thought is that conflict is making things a lot worse.
What I'm doing now:
Generally I'm trying to ignore the behaviour and make good things happen at the car.
Being more prepared at the car before I put the dog away i.e. having one door locked and the key in the other just waiting for a quick turn and throw the boot down. I also throw in a little treat to distract her while I lock up and close.
To be honest I think this is the hardest part for me as I feel I'm running away from the issue rather than addressing it. But this could also be part of the problem....it's not in my nature to allow that behaviour towards me or mine and "dealing with it" in my own special way has brought more trouble that I bargained for.
Ideas?
