Suzie in Battle Mode, originally uploaded by dagnyg.

Rat terrier Suzie in full battle mode. Hair on her shoulders and back standing up, tail in flag waving position. Thought it’s hard to see in this photo, she is showing teeth too.

What prompted this? She is on the back of the couch looking out the front window at a squirrel.

Taken with Nikon D600 at 1/20 second, hand-held.
