Puppies are pooping every ~3 hours, plus Mabel poops twice a day. These tiny geniuses usually cry to go out, so we probably clean up 10 a day inside, and the rest Phillip is trying to track down and move to the edge of the yard. Even so, we step, sit, kneel in poop all the time. So do they, which does not bother them, and then the crawl on us and lick our faces.
The yard keeps us sane!
