According to data collected by IBGE and updated by Instituto Pet Brasil, in 2018, there were 54.2 million dogs, 23.9 million cats, 39.8 million birds, 19.1 million fish and 2.3 million reptiles and small mammals in the country. reaching a total estimate of 139.3 million pets(GERALDES, 2019). With so many pets in Brazil, the question arises: how does the law view animals? How are they treated by law?
Pets have increasingly gained connotations of family members, as opposed to the idea that they are simply human property. The idea of Animal Law is also emerging, which would be a set of rules and principles that establish the fundamental rights of non-human animals, considered in themselves, regardless of their environmental or ecological function (ATAIDE JUNIOR, 2018, p. 50).
The Universal Declaration of Animal Rights, of January 27, 1978, of which Brazil is a signatory, considers that every animal has rights and should not be subjected to mistreatment and cruel acts. It also determines that animals have the right to live and grow according to the rhythm and conditions of life and freedom that are specific to their species.
The Federal Constitution, in its article 225, section VII, establishes that fauna and flora must be protected, and practices that put their ecological function at risk, cause the extinction of species or subject animals to cruelty are prohibited.
