Of course the other option would be to get two dogs, maybe one older and one young. They would keep each other company as well as offering twice the security and love.

My dalmatian does this often and it is related to him having urinary crystals. He is on a low protein diet and has stopped "attacking" his penis with such vigor. I think he did it because it was causing a stinging burning sensation. If your dog continues I would recommend getting his urine tested for crystals.
