**Sending Good Vibes** your way, @Saalwi. How horrible this little bug is!
I'm a bit obsessive compulsive already, but if Grandma saw me out there "washing the yard", I think she'd call the KooKoo Wagon to pick me up.
In listening to your story, it makes me leery of everywhere! How common is this? Clearly, there's no way to "prevent" it. Anywhere there's dogs, there's poo. Ugh. I feel for you and I too would also be worried. (And I'm not a worrier per se)
Hang in there!
