6 yo female lab. Last night, about 3am she was crying so i went down and she was standing by the door. Let her out thinking she needed the toilet. But she just went out and lay on the grass and would not come back in - not even with the offer of food. When we did get her in and we went back to bed she did it again and again to the point that DH ended up sleeping on the sofa with her on the floor beside him as we were worried she was ill, however she seems fine.
All day today she has stayed outside. She seems well enough although she didn't come looking for her food at 6 like she usually does. It was 8.30 by the time i realised she hadn't been fed.
This is not usual behaviour for her and i wondered if anyone else had a dog that did this? I am rather dreading going to bed as i suspect she will start up again. We plan to just ignore her if she does.
