What can I do to maintain stray dog from using my front patio as their outside john ? ...
Answers: there is an out-of-date wives tale that states if you enjoy water surrounded by your yard, the dog will assume the sea is for him, and then choose not to deficate where on earth it drinks.
apparently anything water will deter dogs from departing any deposits.
So... water surrounded by a bottle sitting on the lawn. Water within a small dish. water surrounded by the garden. water bird narrow road.
best of luck i know how annoying it is!
call dog catcher,
put some amonioa contained by a pan surrounded by yard
