Johannesburg - Children are being forced to imitate real dog fights, with bets placed on which child would cause the most injuries through biting and scratching, The Star reported on Monday.A school in Springs, Ekurhuleni requested the help of Inspector Wendy Wilson from the National Council of SPCAs in June, according to the report.The school's principal, who was not named to protect the identity of the children, was concerned that pupils returned from break time with torn clothing and injuries, Wilson told the newspaper.Teachers discovered that the children fought each other in dog-fighting role-play, while other pupils placed bets on who would win.The children were doing this reportedly because adults encouraged them during weekends to take part in actual dog-fighting as well as role-playing."They rip into each other. The play is aggressive enough to cause each other injury," Wilson was quoted as saying.Other children placed bets of between R2 and R10."The winner of the fight then gets to mate with a younger child as reward," Wilson told the newspaper.She was not sure whether this role-playing moved on to actual copulation.The Gauteng education department said it was made aware of the allegations early last year."The department had contacted the SPCA to request their intervention," spokesperson Phumla Sekhonyane was quoted as saying.
