I have just been to two lovely little dogs, a Westie and a Miniature Pinscher.
Both bark in a frenzy when someone knocks on the door. Westie Jock barks non-stop when out on a walk.
I group barking roughly into four types – one when the dog simply wants something, another when the dog has been trained to ‘speak’. Then there is barking in play. The fourth and most common type of barking that I go to help reduce is what you could call ’emotional barking’.
