Recently, Tico has been barking in the middle of the night at what appears to be nothing. I wake up, walk around, go outside with him... nothing. Sure it could be an animal or something, but it's starting to really get to me. I haven't had a full nights sleep in a couple weeks. He used to sleep through the night without a sound. Sometimes he'll be barking at the end of my bed, looking out into the hallway, at a shadow on the wall. What's going on? Is there anything I can do to get him to not bark at every little thing he might be hearing? He doesn't bark like that at all during the day (he's actually really chill) - but at night he starts to get agitated.
A friend of mine told me I should to try skullcap - it evens you (dogs and humans) out. Has anyone tried it with any success?
