Dabbs didn't flinch when I presented her with a pair of feet in a particularly disgusting state after a weekend spent camping, largely barefoot, in a country field. She trimmed my toenails sympathetically and shaped them neatly (most chiropodists simply hack them away, so that there's nothing left to varnish), then excavated the nasty crevices down the side of each nail to prevent the formation of tiny corns.
