Birna is now at home with Daniel and Sally and her older Icelandic Sheepdog "sister" Timber and doing very well.
Trygg has learned, well mostly learned, his name, and "Come!" and "Sit!" And it's only taken a few tries. More commands to come. All three are mostly sleeping through the night. Trygg wakes up at around 3:30/4:00, whines a little, which I ignore, try to ignore, and goes back to sleep until 5:00. Soon daylight savings time will come and when it does that will be 6:00 a.m. Which sounds much better to me. He's not housebroken - yet. And we're so far not even trying, well, trying hard anyway. His bladder is small still.
