Secret Service moves:
What a good boy!
He really ran and knocked over his little human to move him out of the way of the oncoming attack, then stood over him and fought the other dog off, then when the other dog tried to attack again, good boy bolted over and swept the leg like freaking Liu Kang!
Then back to mom and boy, standing in front of them like "Don't worry, if dat foo comes back I'll buss him up again."
