Sinki security team

This morning I heard Greta growling fiercely. Arlo started barking. I went into the living room to see what had offended them. They were standing at the window looking into the side yard. Hackles were up, and I think I saw Greta's teeth.
I peeked out the window. Our neighbor has a new lawn ornament. And our dogs feel they need to protect themselves, their humans, and their den from the 18" tall, wooden uncle Sam with a flag.
I let them out of the house, they ran toward it, stopped 5 feet before it and started to bark their fool heads off. A minute later, they had apparently gave him the what for and trotted off to threaten the squirrels.
