The following is a uproariously comical video of a pup doing what he does best! He is being defensive, making certain the vacuum knows who is boss!

Don’t cross this dog! He’s a lean, mean vacuum challenging machine!

Something tells us the encounter was part dare and part fun. Certainly the German Shepherd was curious, barking at the vacuum cleaner, but you had to think there was a bit of a smile behind that growl. After all, every pooch likes something mysterious and new!
