It always cracks me up when I offer Hathaway something to eat and he sniffs it first, like there's the remotest chance he will not take it.
The only thing thing this dog has declined is leafy greens without dressing. Even then, because he is always the gentleman and his manners are impeccable, he will still daintily take the lettuce or baby spinach, just to spit it out when he thinks I'm not looking. The same thing goes for raw mushrooms; he prefers his fungi sauteed or on pizza.
Still, offer him things he loves: a nut or a bite of bagel, piece of apple or his favorite -- banana -- and he will take a whiff before accepting your offering. Maybe he's checking the vintage. Maybe he's whetting his appetite. Regardless, his devotion and his pleasure are food. Indulge him, and he will worship you. He eats as we all should: with love and gusto as evidenced by his prolific and appreciative drool, if not by his svelte body.
Maybe we should all follow our noses.
