We have three dogs; two of which are B's.
There is a lot of snarking between the two B's,which bugs my dh but not me. It alarmed me at first until I realized that it's really just a bunch of noise. They are loud, but no one ever gets hurt. Most of the time, depending on what they are fussing over – often it's the best spot on the big pillow --I just ignore it and let them work it out.
I used to try to stop Jazz from getting snarky at Keoki when she was on my lap and he'd come into the room, but now I let it go. For them, it has become yet another game. Here's how it is played:
Jazzy is sleeping on my lap. Keoki walks into the room; Jazzy growls. The growling gets louder and meaner sounding as he comes closer. He jumps down into puppy-play position,then bounces back up and hops away, returning quickly to repeat. Jazzy leaps from my lap to charge him; Keoki dashes down the hall w/Jazz in hot pursuit. The Basenji 500 has begun and they will usually play for at least ten minutes and both forget about the lap.
When Gypsy {non-B and old} comes into the room and Jazzy growls, I can usually turn her face away and tell her to "be nice". For those two,that does the trick pretty well because Gypsy just ignores her and goes about her business --- she's too big to get on my lap anyway, and Jazzy knows that Gypsy is no competition for "the spot".
