Good Morning   Can someone please help me?   I have two English staffs, the older male has become very aggressive towards the younger one over the past 2-3 months, they are 3 and 4. last night my wife was bitten as we tried to break up a fight. the older one has attacked out of the blue, for example the other dog just walking into a room.    they have been on and off with each other over the past 12 months however the las 2-3 has escalated to fights every few days.
