The American Society for the Prevention of Cruelty to Animals focuses heavily on the issue on dog fighting. There are various levels of dog fighting. There is “street” level, which means that the dogfights are informal because strict rules and regulations are absent from the matches. Another level is “hobbyists”, which are fights that are formally organized. They are mainly scheduled for income and speculators. The final level of dog fighting is “professional.” At the professional level, owners usually have more that fifty fighting dogs and carefully examine the specific breed, lineage, and winning history of each dog.
