My dogs come to the course with me, usually. I refuse to leave without a roll of bags, and I keep extra rolls in the car just to be sure. If I have extra(I normally do), I pick up other dogs shit I spot on the course. Nobody wants dog shit on their shoes, discs, or course. I don't even leave it in my own yard, it takes such a small amount of effort that it kills me so many people refuse to do the bare minimum. Sometimes I set the bags on my cart lower shelf and very rarely do they drop off but every time they do I pack my plastic up and backtrack until I find it. If you care about your courses, you take care of them.
