Is there something that this guard dog can sense?

Dogs can often sense big or small threats better than people. Today we think Samson is sensing a threat that is small, maybe very small. Watch Samson loudly warn his owner of the dire threat and then hesitantly go outside to check it out. Once Samson has cleared the area, he seems to calm down and possibly reflect on what a good job he did today of protecting his house. Good Samson!
