Shyla is finding happiness in Labrador Valley. The complete change in routine and setting since our Black Dog's death has helped her. Because our patterns have changed, the absence of her brother is probably less jarring to her.
I keep talking about play for our dogs because I think that it is so key to their happiness. Just outside our door, they can play with abandon - which helps them so much!
Shyla is as enthusiastic about playing as Hachi is. Their bond is growing through play.
One issue that has caused all of us distress is Shyla's separation anxiety. We are learning to adapt our habits to her need to be right next to one of us at certain times of the day (at the times when she used to be with our Black Dog). For example, in the evening, we have her in an ex pen between our chairs while Hachi is free. Shyla is calm because she's next to us, and Hachi is calm because he is free to move around.
Just before walks, we are now trying out having each of us have a dog on leash while we get ready. They are both quiet and calmer if they are right next to us.
And then they go outside to do this!
