With that one female, it wouldn't have mattered what you did. I had never had a puppy I couldn't fix that issue in before or after (even her kids, grandkids and great grand kids). That is always why I felt that it was a created behavior do to all of the pups still fighting in the group for their meals at 9.5 weeks.

I just prefer to feed the dogs in their crates. They are more relaxed, no one bothering them or another dog staring at them, no pressure.
