nice write up here. If you're wondering about her name, it comes from a character named Asuna in the Japanese anime Sword Art Online.
Asuna is a wonderful dog. She is very affectionate and quite smart. We knew she was going to have a high energy level but I don't think we were prepared for how high was high. We need to give her a lot of exercise and walk her a lot. She loves to play ball with us but at this point that mostly means that she keeps the ball away from us. "I've got it and you don't," is her usual way to play. But she is getting better. We have her in training classes but I think they are mostly for us. Asuna knows what she is doing and is waiting for us to catch up.
In case you are wondering, the picture on the left is the "original" Asuna from the anime.She has bigger eyes than the "real" Asuna.
