I have had my approximately 5 year old pitbull rescue since January 2009, and she has never behaved this way.
She is a very affectionate dog, but most of her day is spent sleeping in her dog bed.
I work from home during the weekends but leave for an hour or so to go to the gym. Since I've gotten back this morning, she has been right at my feet. She even layed right outside the shower stall on the bath mat while I was getting showered. Totally not baseline behavior for her.
I live in a multi-level house, and she's literally followed me up and down the stairs with every trip, when she usually just lounges and waits for me to come back up to my office. When I got ahead of her during one trip upstairs she even started whimpering a little, as if to say "Wait for me!"
I don't know if she is having an issue or she senses something wrong with me, but I'm frankly a little nervous! She ate and went out as usual today, so nothing seems off course in that regard.
Did anyone else have this experience before?
