What I don't understand is why there are no trails if the wolf is moving across the frame faster than the shutter is? I would have thought you'd need a shutter speed of about 1/500 to freeze that wolf without trails, not 1/30.
I clearly have much to learn about flash!

OK - so
technically there is a blur of the wolf in the frame. We just can't see it because it occured when the shutter was open in complete darkness. Like a black cat in a coal mine.
Sometime during that 1/30 of a sec the flash fired and lit the wolf. The flash lit the scene for maybe 1/10000 of a second during that thirtith of a second providing enough light to record the image and also freeze the motion.
