Nonetheless, accusation of cruelty in the USA persist. The PRCA acknowledges that they only sanction about 30 percent of all rodeos, while another 50 percent are sanctioned by other organizations and 20 percent are completely unsanctioned. The PRCA opposes the general concept of animal rights, but supports animal welfare. The PRCA takes the position that the organization does this and even goes beyond expectation. Not all rodeos are governed by the PRCA however, though organizations governing collegiate and high school rodeos base their rules on those of the PRCA. Nonetheless, certain amateur and "backyard" rodeos are unregulated, and do not follow PRCA rules.
