Fitzi invites Lucy to play. Lucy is having none of it.

Lucy, keeping the ball handy for the next fetch session.
Although Lucy is always ready for a game of Chuck-it!, she still keeps an eye on things.
One year later, this photo still greatly amuses me. Fitzi, right in front of me with stick in mouth and in a very high pounce, invites me to play.
Lucy sort of watches Fitzi race around the yard with The Coolest Stick On The Face Of The Earth.
I thought about cropping this photo to only show Fitzi, then decided that keeping Lucy in the frame added good interest.
Fitzi invites an out-of-frame Lucy to play.
I crouched down to capture Fitzi clutching a very large stick in his jaws. He raced at me, I clicked the shutter button, the exposure meter had to compute before tripping the shutter, then Fitzi leapt at me.
Whoa. Darth Fitzi.
A favourite photo from not quite a year ago – Fitzi inviting me to play.
Eager and expectant, Lucy, presents the ball for its next launch from the Chuck-it! She has to drop it first, though, and within reach. (More often than not I make her sit, butt fully on the ground if only for a second.)
