What do you do when you're hiking along in Switzerland and a big Bernese Mountain dog runs up to you, leans against your leg, and sits on your foot, stopping all forward motion?
Then rolls over, exposing a furry belly and pleading eyes?
And you're allergic to dogs?
You give thanks that he's not a cat, and give him a good tummy rub using one hand only, promising yourself you won't touch your face until you get home and can wash.
Because who can resist such trusting love?
