I love Dogs. Whatever decision you make, I know it will be in Zero's best interest.
I was an Urban Studies major at my University and I'm familiar with CA's and LA's mass transit problems. I'm impressed that you're able to use bikes as much as you do.
The best thing I ever did towards increasing the practicality of using a bike as my major means of transportation was leave the suburbs. Richmond VA is a great place to ride full time, many people think I'm lying when I mention my average fuel cost each month is $30.
