Stop an Alert Bark
I got a 7 month male (purebred) German Shepherd and when there are suspicious sounds or other dogs barking in the neighbourhood he will give a alerting bark. The problem is he won't stop until whatever it is stops making sounds or goes away. I am a female college student living in a basement suite with my roommate so he is of great help when he lets us know of a potential threat and we both love him.
He did me a huge favor one time he started barking at 3AM and I found my auto-lights on outside. I am 100% sure it was another person trying to approach my door.
I want to praise him for letting me know that there is something possibly dangerous outside but I also want him to stop when I acknowledge that there is a possible threat.
