Zarina, please don't be offended, but I am still not convinced that you have truly understood the difference between aggression and rage.
Rage affected dogs (though I only know what I've read about it) seem to be absolutely fine between "rage seizures". The rage comes out of nowhere, a little like an epileptic seizure.
In your last but one post you explained that Raj had none of the signs of rage, then went on to illustrate by giving examples of possessive aggression.
I know I am no expert, and if anything I have said is incorrect, then I hope that someone with more experience will correct me. But from what I understand of the condition, it is in no way linked with behavioural issues.
I agree that no matter how reputable your behaviouralist is, if the first conclusion reached, without meeting Raj, was a diagnosis of rage, then you should consult someone who is willing to be more open minded and realistic.
I sincerely hope that Raj is not affected with rage, if he is then the only remedy seems to euthinasia (?sp), and it is for this reason that I urge you to work carefully towards diagnosing his problems.
I do hope that all will turn out well.
