I've seen this lady in my neighborhood walking her dog with this thing for probably close to a year. Today I finally ran out of my house after her (literally)
It is supposed to be a scoop, but you can also just hold it under their butt when they squat. The plastic bags you get at most grocery stores fit on it with no problem.
Picking up poop grosses me out to the point that I gag, especially when it is a fresh 'deposit'.
I'm ordering mine tomorrow! YAY!!!
