How old is your pup, what vaccinations has he/she had and when.
I have not used bleach in a yard or a setting other than hard surfaces. Frankly, I don't see that as a solution as spread can (and very often is) done through contamination of your shoes or other objects when unknowingly walking through contaminated areas.
I would be most worried about rest areas, dog parks or exercise areas, pet stores... I would avoid those areas and interacting with unknown dogs (unknown vaccination status) as much as possible until the vaccination series is complete.
