Lemmy is barking for a long time right now

My friend has complained of the second dog, Lemmy, for a long time. He has something behaviorally/emotionally that he's struggling with. He heard something outside just now and cannot settle down and stop barking. He's been barking for the last 15 minutes straight and it's often like this, poor thing. When I talk to him, I hear him dejectedly tell me that he feels a lot like I do. He has upsets psychology that he can't calm down from and hos home environment doesn't help. Princess Kitty Cat psychically "came over" and said she has help from the animals at the Rosslyn bc we have many dogs at the Rosslyn that are like this, too. Princess Kitty and the Rosslyn animals have been talking to Lemmy and he quieted a little bit but he's still very worked up, pacing and barking off and on. There's no one outside anymore. :( Intensity in so many beings lives.
