Today was their first time in the yard together. Had to do it...they've decided to be friends and play, and were about to wreck the house. Lib started cornering him a few times, and it looked like her baser instincts were kicking in, but he snapped her out of it with his silliness. They're finally safe to be together. One month and one day it took! Lib is often like that with new dogs here, but it's normally females, and they're usually large enough to defend themselves.
