Dog pooping in my yard - help!

[Regan]

I'm not sure if this is appropriate for this forum, but I'm a bit vexed about how to solve my problem and thought I'd enlist my neighbors' help. I've had a large dog poop in my yard 6 times in the last two weeks - in virtually the same spot on my upper lawn. I live on 43rd between Barrett and Armour. I've never seen the dog, but am ready to get aggressive in figuring out who my mystery guest is. I don't have a dog for a reason - I don't like cleaning up dog poop (my little kids keep me busy in that category)! If this is your dog (seems to roam at night/early morning) - PLEASE stop him. If you live near us and happen to see a large dog - please let me know what he looks like so I can keep any eye out for him and his owner. I'm really tempted to install video cameras.......any other suggestions for remedies are much welcomed!
