Interesting question!
I've never known anyone who is considered using Prozac to treat aggression. For me, drugs r a ''extreme last resort'' if they're even an option AT ALL.
I have known people in Rescue to utilize Clomicalm for *seperation anxiety*..but only after training, crating, alternative methods of confinement, de-sensitzation & use of something like Rescue Remedy has failed. And even then- the drugs r used when the behavior is so severe that the dog is a danger to itself.
I hesitate to think just how severe an aggression problem would have to be, before I would *personally* consider using a drug to dull it. The prevailing question in MY mind would be..if a dog is aggression is THAT severe, especially if it is unwarranted aggression towards people, then WHY is the dog still ALIVE? Using a drug for something as potentially dangerous as human-aggression..is a far cry from using it to help manage seperation anxiety or thunderstorm anxiety, or helping to manage a puppymill rescue, etc..
And if a severely aggressive dog is in the hands of someone who is NOT equipped to manage it using conventional training methods...(or who is not wise enough to know when to draw the line & opt for euthanasia)...it concerns me that there r those people who WILL use Prozac as a ''quick fix alternative to training'' with a severely aggressive animal.
Like I said, it is a situation I have never experienced..and I have dealt with dogs who have aggression problems (I even owned one). There may be a legitimate use for Prozac in dealing with aggression that I have not thought of...but my first reaction here is to think aggression is NOT something u ''fix'' with drugs. In my mind, u either fix & control it through behavior modification, or u entirely remove the menacing dog from the general populace (euthanize). JMO, but I will star the question for you, I am interested in what others have to say.
