As a dog owner, I find this thread kind of disturbing.

The best way to have peaceful neighbors is to BE peaceful. I would be so upset and so angry if my neighbors had an issue with me, and instead of coming to me, they went to the authorities first; and next thing I knew my pups were taken away from me. That is not fair to them.

And, if my neighbor came to me and explained that they had stepped in my dog's doo and it ruined their best pair of sneakers, and asked me nicely to please clean it up, I would totally respect their wishes.

An idea would be to take over some dog treats/toys, and explain that you love dogs, but hate their poo. Tell them you stepped in it, and it is very incovenient for you when you are in a hurry. And give them the benefit of the doubt, and time to get their act together.
