Duckitup- No I haven't figured it out! She is still doing this and it's becoming disruptive. You're describing what she does. Last year when she was a year old this time she would do constant gathering call when she heard me in the house and would stop when I came outside, now she does it when we are out there with her and stops when we leave. Like yours, she acts fine with her routine otherwise. She is so loud and does the mouth open gesture and will stop most of the time when I pick her up but starts right back up when I put her down as long as I'm still around. At first I thought it was related to feeding schedule as I've tried to retrain to feeding a few times per day only vs having food available more often. But it's been going on for so long now that it doesn't seem to be related to anything in particular. I just wondered if this was normal and if it'll stop at some point....my husband has talked of finding her a new home because of it. I don't think I could ever do that but it has become that disruptive.
