we need more info.
age of the dog, background, how you have been training him, any serious health problems, the dog's daily routine including the amount of exercise he gets, what does his body language look like during these "rampages" etc etc etc
everything you can think of
first thing I would say is he needs a trip to the vet regardless, to rule out any potentional medical issues that may be contributing to this..then you need to try to locate a behaviorist in your area.
will tell more after you give the info requested..
