Get him done now they can be done from 6 mnths,Archie has not bothered since he was done 3wks ago & he seems more settled ,he was the same at night after his feed he would start his humping,also he got aggressive & dominent so we had no choice but to have him done,sad but true.
My husband was against him being castrated until Arch bit his mum,she tried to stop him humping on his toy dog, it could have been a child. DO IT NOW FOR YOUR OWN PEACE OF MIND. X
