Actually my 9 1/2 lbs Shih Tzu poops much bigger than my Yorkie who weighs 13 1/2 lbs.
I'm with all of you calling your back yard "mine fields "!
My husband tries to clean it up every other day, but their still seems to be a lot and the neighbor lets his big dog poop in our yard.
My husband at night, shovels it up and throws it back into the neighbors yard. Hee! Hee!
After all it's not from one of our dogs. I don't know how people can let their dogs do their business in other peoples yards and not clean up after them.
I'd never do that.
