It is a weird thing to see this happen…they are so sensitive. We went through a minor phase of what you’re talking about. As for advice I’d have a chat with your vet for a few options. We had some decent results by doing this: Whenever the dog would get sensitive over something that was not directed at him we’d make a big point to call him over, reassure him, pet him…that sort of thing. I know this is really not an answer to the problem but it seemed to help. Now when he gets a little weird about something instead of thinking it’s directed against him he sort of waits for a second to see if we reassure him that it’s no big deal. Even a “It’s okay buddy!” seems to let him know he’s not in “trouble.”
