Bleach isn't a hazard as long as it's rinsed well.

At the shelter, they were using bleach in a too-strong solution on the floors and not rinsing well. Several of the dogs developed hair loss and mild burns on their hips and legs from laying on the floors. Now they use a lot less bleach in the cleaning solution.

Heloise did a test a few years ago that proved that vinegar killed as many bacteria as bleach. I used vinegar to clean the carpet after puppy accidents and it seemed to work well.
