Which was teasing her from a limb above. She guarded her "swimming" pool to keep the squirrels from drinking from it. I put the pool - a round four foot kiddy pool - just far enough from the tree trunk that the squirrel could get "caught short" in it's get-away, but close enough to be irresistible. This arrangement set up a tension between our dog "Babe" and the squirrels. She caught one on occasion.
