Barking at the kids...
Over the past 2 weeks or so, Lola has started barking(quite viciously) at my son and daughter(9 and 2) when they go up the stairs to get to their bedrooms. It only seems to happen when they are alone. If myself or my wife are with them, she's just fine with them being there. Is this normal behavior? She is very much a herder. If one kid strays too far in a walk she gets anxious and starts doing a low whimpering noise, but the bark she is aiming at them when they come up the stairs towards the bedrooms is similar to what she'd do to a dog barking at her from behind a fence on a walk.
Is this something I or my wife should correct? Should I have my son go over and tell her "NO!" in a stern voice? It scared the crap out of him the first time it happened. I don't want to discourage her from being alert, but she should know the kids are supposed to be there.
Some background: Lola is 7.5 months old and was crated in the living room. However, our kids(9, 2 and 1) would rile her up when they would run through the house. We decided to move her up to the bedroom, but she seemed to toss and turn quite a bit so we put her just outside of our bedroom door in the game room. This room also has a view out of a large window to the front yard, is open to the whole front of the house and is closely located to our room. She's done really well there and is generally doing great as far as walking/basic training goes, but is still crated because we don't want her to play too rough with the kids. She is out often and leashed to control her if she gets too excited with the kids.
