Little Froggie…………..
Disclosure>we have 4 dogs, but they run in a private fenced in 1/2 acre and humans are not affected by their waste.
I have a number of questions:
Who owns this land?
If it is your landlord’s you can ask him/her to post signs re: no dog walking, no trespassing..violators will be prosecuted. Take video of the offenders and go the police.
If it does not belong to your landlord make a complaint to the health department about the unsanitary condition and let them handle it.
BUT: it may be that your children don’t have the right to transverse this land to access the school bus and you may be stirring up a hornet’s nest.
