Dogs are very territorial creatures. They don’t like when they think someone or something is infringing on their territory.

So when this great dane heard a wolf’s howl come from an iPad, it got seriously confused. He knew he heard an intruder, but couldn’t pinpoint exactly where it was coming from. Watch this big guy’s inner struggle as he hilariously tries to decide what move to make!

I especially like how the other dog doesn’t seem to care — not one bit. Well, at least he’s got his big bud to look out for real (or imaginary) foes.
