That ridiculous, curved inertness. The way you could hold it out and the dog would just look at it, perplexed. The fact that it reminded me of a microphone and I could speak into it, and the dog still wouldn't object.
Why paws--especially the back ones--held such fascination for me I am not sure, but they still do. Fortunately I have been able to channel my interest into harmless and perhaps even productive pursuits, like holding those paws steady as I massage them and trim the nails, or coaxing them into a "shake" with a touch and a hot dog.
And fortunately, over the years of coming into contact with so many different sizes and shapes of dogs, my interest has broadened to include cool, fresh noses, flappy or satellite dish ears, silky or hairbrush-like fur--indeed, the whole dog package.
Drink it in, and really focus on it.
Did the paw make you smile?
