Annie running is pure joy for both her and me. Of all our dogs, past and present, she is easily the fastest and most agile.
I'm particularly pleased with the muscle development in her right rear leg, which now almost matches her left leg, upon which she relied after her surgery at six months old.
She's hard to pin down with a camera. My approach is to enable auto ISO and track/shoot no slower than 1/3200 and sometimes I get lucky.
