There are a lot of dogs with absolutely no ball drive and there is nothing you can do to change that.
For some dogs you just have to show them how fun the ball is before they get it and you can do that by putting it on the end of a leash, set it on the ground, and then move it quickly around with you sounding excited. It may take a while, but the dogs that have some ball drive will catch on.
