You'd think he was lazy, but then you notice that he eats more bread crusts than meat, and you realise that he's sleepy with starvation and sadness.
What to do? You could buy meat and feed him every day, thereby making of him a devoted servant and your dog by default. But meat is expensive and you can't have a dog. He's not your responsibility. You don't know whose responsibility he is, but he's not yours. Think of all the repercussions! He's probably full of fleas and deathly illness. And there's thousands like him. Far better to wait for the dogcatchers to shoot him - best for everyone, really.
Oh, these dogs. I saw a yellow family of mixed-up labradors last week, two adults and four puppies, gambolling in the gutter. These dogs will break your heart if you let them. I have a ritual response now: I pray. I ask God to let their suffering be mild, and their lives short, for they must surely break His heart as well as mine.
