I tried to wash it off, but I got sick the next day.
Do you know what the cause of your sickness was?
I think so.  It must have been some dog shit that was in front of my house
Dog waste can be very disgusting, so it is understandable that you felt physically sick after being in contact with it.  As long as you managed to clean everything, you should be okay.
Somehow I feel good. Glad I could scrub it all off.
It's understandable that you felt repulsed by dog feces. It's great that you took action to remove it so that you do not have to see it again.
