Since 2008, the Swiss Animal Protection Act protects not only the welfare but also the dignity of animals. This article explains the concept of the dignity of animals in the context of the Act. Weighing of interests is applied in a specific situation to answer the question of whether the dignity of the animal is respected or not. With this method, the strain imposed on the animal and the interests involved in the situation are evaluated and compared. The seven-step model for the weighing of interests is explained in detail. How the weighing of interests deals with practical questions is shown with the example of kangal fish used for therapeutic or recreational purposes.
