Thanks for the encouraging words from all of you! Puffy does know his name, but won't come. He's usually frozen in place with fear. I have to carry him where I need him to go. He won't eat yet. I'm going to leave food in his crate tomorrow when I go to work. Maybe he'll eat when no one's around.
The problem child is actually Nash. He's starting to show signs of resource guarding and went after Maddie this morning and again this afternoon. Jealousy, I imagine. Jeesh...if it's not one thing it's another. He'll need to be crated during feeding time for awhile.
