If both of you are worried enough to think about her having protection while jogging, I think she would be better served with a firearm, even a small one like a P-32.

If she has to go the non-lethal route, I would recommend the pepper sprays that come in the form of a pair of 1 lb hand weights. She can use the spray to slow 'em down and bash their skulls in with the weights immediately following. I'm not joking.
