Well here's something i got of a book i own...I tryed this with my oldest
dog Snuggles and i only had to do this 3 times and the problem was solved
When a dog continues to bark
After sounding his alarm and being calmed down, if he/she still continues
to bark excitedly, speak directly to him/her with a commanding "Quite!" if he/she still doesn't get the idea, demonstrate by dabbing a little lemon
juice on his/her tongue and holding his/her mouth closed (being careful
not to cut his/her breathing passages) for a moment. Remember that
you're teaching, not punishing, so don't further excite him/her by yelling
or hitting him/her. Release him/her when he/she is calm again, letting
him/her know everything is all right...
