As far as her being “unhappy” because you’ve “awoken the instincts” or whatever, no, that’s not gonna happen. She would be fine.
However, is it gonna be beneficial, i.e. enough to actually teach her much and get her in a good working frame of mind? I honestly don’t know. Maybe others will have a better idea.
My experience has been, with really keen dogs, they have to be worked often, and if they are given a couple weeks off, they come back kinda nutcases, LOL, and we have to spend sometimes almost a whole session working the crazies out. I suppose it depends on the dog.
