We have a little Shiba Inu round the corner. His owners keep him inside an electric fence in the yard and he NEVER stops barking. You can hear him for blocks.
I have a barker, but I don't let her bark outside for hours.
Mine isn’t a barker unless he hears someone at the door or is saying “hi” to one of his dog friends. He does have his lil’ howls, though.....just to hear himself, I Think.
He has a deep basso-bark that sounds like it should be coming from a dog twice his size, hehehe.
