I've got a Wheaton x bitch here about the same age and I was the same with her,just couldn't take to her. Severely needed to grow up but just wasn't doing it,testing my patience to the max every time I had her out. Doing nowt wrong in anyway work wise,only had a few rats and rabbits and doing fine on both. Anyway I've given her a good bit more one on one time and she's changed for the better,I'm actually starting to like the bitch and she's getting a pleasure to own. I know not everyone works out the same though.
