Perhaps. On the other hand, toddlers don't look like sausages and shout "food", "food" like wiener dogs do.
To a wolf, they do. When I first read this I assumed it to be mistaken ID for a big domestic dog (esp. the remark about it looking like a oversize shepherd.) as a stray or feral domestic will tend to be a lot bolder around people. Wolf packs will (normally) avoid large groups of humans or even signs of human activity. The classic "lone wolf," that either operates on the outside edges of his pack's territory, or has completely been exiled from it, can be entirely unpredictable without the enforcement of pack rules to define his behavior.
