Loki is just about all better now. I had gone away for a conference this past weekend, so Yun took care of Loki for three days. The first day that I was gone Loki didn't eat breakfast and was throwing up yellow, frothy bile. According to our research, vomiting yellow frothy bile is an indication that the dog is too hungry. But Loki wasn't eating! We were all worried about if this new lack of appetite and vomiting was related to his respiratory issues or if this was something new.
Later that same day, Yun reported that Loki ate and seemed to be back to normal. Yun's hypothesis was that Loki missed me. Aww, poor doggie.
Yun also reported that Loki only wheezed once in the past three days. So it looks like he's all better now.
