Hi,
I have a 4 year old black lab named Abby. She's a pretty well-behaved dog (much better than when she was a puppy!), but she goes crazy when someone comes to the door - she charges at it, leaping up at the glass, barking like mad. I believe there may be an element of protectiveness in it initially, but it's mostly excitement. She stops barking as soon as the person enters, and although she's still excited, the level of excitement drops too.
I've watched the SitStayFetch video on problem barking, and as they suggested, we've been removing her to the bathroom for some quiet time every time she barks at the door. If the person at the door goes away, then she calms down nicely and is let out. If the person comes in, then she continues to bark in the bathroom (and moan and cry) until we let her out, or until they leave. So, this approach doesn't seem to be working.
Any other suggestions? I run a dog-walking and home-boarding business, so I often have clients bringing their dogs over, and it's rather embarrasing!
Thanks,
Ali
