It is not the projectile that caused the most trauma when shot, given one that holds together well. It is the hydrostatic shock of something travelling at a relatively high velocity through muscle and tissue that is composed of a lot of fluid. This fluid (blood, water etc) cannot compress and goes on to cause further tissue damage. That is why the "tumbling" rifle bullets caused so much damage to the victims.
In the case of frangible rounds the kinetic energy is dumped into tissue rather quickly, and the resulting fragments do tear tissue and blood vessels, which leads to more extensive wounds and why there has been a movement to ban frangible projectiles in some places.
Personally, if it is necessary to shoot someone it is not to either kill or wound, it is to stop them inflicting death or grevious bodily harm on either yourself and another and under circumstances where no less level of force will achieve this.
If you feel you need a less than lethal option then as said above, carry some pepper spray. Otherwise select a decent projectile (what your local law enforcement department carry is ideal) and rely on "stopping" any offender with the least number of rounds of required and in the shortest possible time.
Oh, andvthrough experince pepper spray really works well on aggressive dogs. I once executed a search warrant when the offender was not home and had to spray a dog inside before I could get through an open window. When I had to go back post arrest to collect items we had not known were stolen the dog appeared again but ran as soon as I presented the can of spray.
