I was thinking back to when we visited Zhoie at 8 wks. There was 5 in her litter, 2 girls and 3 boys. The first born was the other girl, and she was pistol..came running and was trying to climg the xpen, LOL. The one male was following right in her footsteps.
The other 2 males and Zhoie was more laid back, snuggled to each other. Would play hard for awhile and go back for snuggles.
Once Zhoie relaxed with us, she was a snuggler, but I noticed she didn't want to rolled on her back. That held true for a long time after she came home. It was like she had to learn to trust us, could that be?
Now, Pat or I walk up to her and she flops the little belly up for rubs, LOL
