Wee Wednesday "Weader": Mighty Small

I have a guard dog,
A canine toughy.
He keeps me safe -
Never mind he's fluffy.

He barks really loud,
At the front gate.
If you dare to enter,
His teeth are your fate.

Cover you ankles,
My dog's not tall.
But he is courageous -
A superhero size small.

Huge thank you to this week's Wee Wednesday "Weader", Alexa and her superhero dog, Mason! (Bear makes a special appearance at the end of the video, too :)
