The puppy suddenly started flipping out when my mom isn't home at night a couple weeks before the old dog died. She used to sleep in the room with him and it helped somehow. But now I have done everything I know and he is still barking. He slept for a while but if I take a deep breath he wakes up. I even gave him a little sedative. I think he's getting a little more. He is so wound up that he's never going to shut up and I need to get downstairs to get water so I can take my pills (way late because of him) and I can't take the barking anymore. I have in the course of a month tried everything. Leaving him alon in his crate feels mean but it does not good from me to be laying there while he barks at me.
