- Poop size matters. This is not true simply because of the weight, but because of the need to spread your fingers wide to grasp it all. Stretching a bag causes weak spots, which can lead to tears.
- Surfaces matter. If you’re picking up poop on paved surfaces such sidewalks or streets, or on mulched areas, you can abrade the bag or even cause a puncture.
- Closures matter. Even if you get all the poop inside the bag without a problem, you need to knot it shut without having any poop above the knot. Poop has a way of spreading itself where it’s not wanted, including near the opening of a poop bag, which can get on your hands when you’re knotting the bag shut or carrying it afterward.
