Does he bark and bark and bark and bark and bark and bark like ours used to?
And bark some more?
He only barks when someone slips up on him. He HAS to be around one human at all times. So, if he knows only me and my wife are home, and someone appears at the door... or if our son gently knocks on the door... lookout. He sounds much much bigger than he is.
He respects aggression it seems. If you just walk into the house, he probably won’t bark. But knock gingerly... lookout.
I have heard him bark 4 times in 5 weeks.
