Mexico is considered the second most important centre for bullfighting in the world, with a tradition that dates back more than 500 years to when Spain first colonised the country.
Many people feel passionately about the sport, saying it is part of their culture of heritage.
But with about 9,000 bulls being killed in the country each year, many others have questioned whether bullfighting should continue.
Now, authorities in the capital, Mexico City, are considering implementing a law to ban it.
