Again it's not really important for changing the behavior itself but protection from a threat that isn't classified a threat to us but is to the dog is still protection. It doesn't mean the dog is super fearful per se it just means there is a difference in opinion between what constitutes a threat between you and the dog.
In protection work the dog isn't usually allowed to make that determination on his own, it's instilled in training or put on commands. The dog flipping out or reacting to littler stuff doesn't always mean nervy sometimes it's just boredom and it can be relieved through the addictive reactive process I described above. Sometimes it's mistakes in leash work that build drive and frustration and that becomes misinterpreted. Could be the dogs drives for resource guarding behavior are stronger and you're seeing a reflection of that.
You could be right the dog could be nervy but to just assume so based on what was written by the op is in my opinion jumping to conclusions a bit. Ones that I've seen start fights on here time and time again especially if someone brought into question the value of the dog. Not saying you did that, just saying I see it a lot.
I'd hate to see some of you guys with malinois you'd just go assuming the dog is a bag of nerves because it's reactive. If you had a malinois that isn't leaning on the reactive side you might want to worry a bit.
In short we don't know what we don't know and it doesn't really matter that much. The solution is generally pretty similar if not identical in this situation. Also how do you expect a dog to know what and who is a threat and what isn't without training.
