Don't know what has got into her! Ever since yesterday afternoon she has been barking and gruffing/growling constantly at nothing. Now this is nothing new in itself, she barks madly at anyone who knocks on the door, barks at her reflection in the window, at random birds flying past the front door etc, but is fine between times. Now she is growling and gruffing at nothing, literally nothing, she was doing it all last night to the point where I considered shutting her in the kitchen just to get some sleep! Every couple of minutes she is making a little gruff sound or a growl, and her ears are up even though she is in her basket, and there is no noise (we live in the arse end of nowhere) no traffic.
Something is obviously bothering her, but what?
We took the Christmas decorations down yesterday, that's the only thing I can think of which might have unsettled her slightly, although I would be amazed as she is normally not phased by furniture moving and didn't bat an eyelid when the tree went up in December?
No visitors yesterday, no one even knocked at the door.
