People who know about canine needs know perfectly well that regular chocolate might be harmful to them.
The attached photo, however, shows the perfect marketing idea by Trixie, which is based on knowledge of human behavior. People thinking about a small reward for themselves or just a moment of pleasure reach for chocolate, and they automatically transfer this behavior to the needs of their dogs. "My dog will definitely feel the same pleasure as me ..." and since dogs generally eat everything, especially from the hands of their owners, they immediately have proof of the validity of their point.
A similar mechanism is also used by pet food producers, who prominently display vegetable or cereal supplements on their products in reference to the trend towards healthy nutrition – yet such items are not naturally eaten by dogs at all. They count on simple associations of "healthy diet" and "healthy supplements", which are easily understood by less aware customers.
Of course, Trixie "chocolate" is a version adapted to the canine organism, and this allows their brand to build strength among aware dog owners. It also builds associations between their brand and the most emotional moments of rewarding one's pets.
