This 2019 law is a secondary law that regulates the application of the constitutional mandate that the Mexico City government guarantees the fulfillment of the more than fifty fundamental rights established in the Constitution. This law addresses the issue of animal protection, specifically in Article 95. Article 95 states that animal protection shall be guaranteed in the broadest way to provide a livable city and seek people's fulfillment of the right to a healthy environment. Even though the focus of this article is the rights of humans and not the well-being of animals per se, it provides a list of eleven important principles tailored around the protection of animals and their interests. Some of these principles include:
- Animals shall be treated with respect and dignity throughout their lives.
- The use of animals for exploitation purposes and any other that could cause them harm will be expressly prohibited.
- Every animal must receive attention, care, protection, adequate food, veterinary attention, and restful rest.
- Every animal belonging to a wild species has the right to live and reproduce freely in its own natural environment, terrestrial, aerial, or aquatic.
- Every animal belonging to a species that traditionally live in a human environment that is not detrimental to the health of the latter and other living beings has the right to live and grow at the pace and in conditions of life and freedom that are of their kind.
- Every animal that the human being has chosen as his company has the right to have the duration of its life be in accordance with its natural longevity unless it suffers from a disease or alteration that seriously compromises its well-being.
- Shelters for the care of abandoned animals will be created, promoting an adoption culture.
