I don't know, but what I do know is not all dogs are alike. Maxwell is quiet and doesn't bark outside of his home. He only barks when he sees activity outside the door or fence at home. There is a neighbor has a Yorkie, tho he is older and he barks & tries to run towards anyone coming down the road when we have walked together. Maxwell, just loooks at him and wonders I think, what is going on. |
