My two play very rough at times and we do step in and recall them,if they persist they will get time out.They also know the boundries and know they are not allowed to do it in the house and charge around like loonies.I never leave them unsupervised ever,I couldn't leave mine to sort it out because if a fight did break out they would fight to the death.
They are seperated at night and if we go out during the day.

They are always supervised at the moment only picked Harlie up on sunday and i'm off work for the week. We are attempting to crate train Harlie for when i go back to work as there will be short periods when they will be alone and this would make sure both are safe especially while Harlie is so littlexx
