68/365 Constant vigilance

The backyard is Buster's beloved territory.

He's on constant alert for intruders, changes, and breaches of the perimeter, whether they pose serious danger (like a cotton-tailed rabbit or crafty squirrel) or merely test his senses (like a rather large blowing leaf).

Not much gets by him.

He systematically investigates all regions of the territory, using his keen sense of hearing and finely tuned sense of smell as his primary guides. And he conducts his surveillance multiple times per day, during the week and on week ends.

This tireless worker never takes a day off. He takes his job very seriously, but will gladly welcome a token of appreciation or simple scratch behind the ears.

I feel safer knowing Buster is near.
