Cody was a breed snob - really only liked other greys!
I had her in a fenced ballfield once (early on) with my brother's lab. Lab takes off galumphing (is it REALLY running??) across the field. Cody let her get 1/2 way across, then took off & ran by her, turned her head & barked at her, then took off!!! Teasing the poor 'fat' lab!!
