A picture of intensity...
This morning, the two met. You can see the piloerection of Shyla's fur just above her tail. You can also see her ears pinned back and how she's almost leaning backward away from the other dog. Clearly, Shyla was not the boss in this meeting.
In this encounter, the tough part was that the other dog moved so that she was between me and Shyla after they'd sniffed each other. Shyla was scared to come past the other dog to rejoin me.
After a stalemate for a short time, the other human, who has won Shyla's affection and trust over the past year, escorted her over to me. Actually, that is rather remarkable - Shyla trusted another human to help her go past the dog who she is afraid of! If you realize how terrified Shyla was of most people a year ago, that's an amazing event.
