The drive you referring to "protective drive" or whatever you call it, are you talking about defensive drive? If so you will screw up a dog very fast working him in a defense, you start with pray and than you bring defense site in a dog. You bring defense first and you will have issues. It's about balance of drives not one drive is better than other. Every single drive in dog has it's function. Without a pray drive your dog would not be able to hunt trust me. This is why every predator has pray drive. Pray and defense are not the same drives. They are not even close to each other. They serve two different purpose. And if your dog don't focus on you it's not because of pray drive but week pack drive.
Some basic drives:
Food drive dog's desire to persist in getting food (not always related to hunger)
Play drive dogs obsession with objects and his desire to entertain himself actively
Prey drive is the dog's intensity in chasing anything moving away - catching, biting, and carrying it.
Fight drive is the dogs desire to initiate and persist in confrontation, both physical and mental
Pack drive is the dogs desire to work with the handler and be a member of a team.
If your dog is more interested in catching chasing things it means that its pray drive is more developed than pack drive and a lot of time is caused by you the handler and your relationship with the dog. Yes some dogs are being produced to have strong pray drive, but that's not a problem as long as you know how to channel it in productive way, actually pray drive is the simplest to work with.
Now if you have a dog with strong fight drive this is when a problem can start, because the dog might initiate the fight (most unstable dogs are the ones with high fight drive, when I say high it means that other drives are underdeveloped or not present, not that you find a lot of dogs that have it).
You use all the drives to train your dog and if you can keep them at the same level that's when you dog will be optimal working dog.
