Daizy does this every once in awhile! We have glass doors. She is just sure she see's something out in the dark. I think that she senses an animal outside. Our dog dakota smelled a bear over 50 yards away...long before we even knew it was there...from inside the house with ALL the doors shut!!!
I wouldn't worry..it might just be a cat or animal outside...that your little furbaby is picking up on! |
