thanks ladies
I think he may have to be desexed for sure!!
Um im not too sure if he was hurding the dog bcos he was on the otherside of the fence and i was standing in the dorrway in a towel!
and your right - he needs alot more "exercise/activites". DH takes them running up the bush for hours in the weeknds but clearly he needs more!
What kind of "work" can i give him to keep him ocupied??
