mate its like they said pig numbers...my arab bitch was10 months and my arab cross was 12 months..but my young male 6 months arab shows signs of now he want some of this action...but i wanted to hold my bitches back a lil to mature a bit first and i think it has worked well as behaviour wise they r well behaved...and i can verbally call them off a pig and get them back on...so my 6 month old male shows more of just a meat headed lugger so he will need more training but he will learn from the older bitches but unless your got country thats has plenty of pigs just let it happen and go out with expirienced dogs as they will show the way for your pup.
