I have a 3 year old Labrador x Border Collie cross who is wonderful with people outside the house and great when people she knows come to the house. But when new people come to the house, she barks, growls and eventually hides. Luckily, she has not lunged or bitten yet, but I do not want it to get to the stage. Does anyone have any tips or advice, please?
