Buy by three things: whether you can open the bag one-handed with a leash in the other hand, the flat dimensions compared to whatever you use now, and what reviews say about tearing. Most of the rest, including most green wording on the box, matters less than it looks. Here is how to judge each part.
Why tearing is hard to predict from a listing
Bags usually fail at the bottom seam or a corner, not in the middle of the film. Thickness plays a part, but so do the resin blend, the seam quality and the bag's construction, and almost no listing tells you any of that. A thickness figure in microns, when a brand publishes one, is a useful clue rather than the whole answer.
We have not published a thickness figure for our own bags yet, and until we do, that is a number you cannot compare us on. What listings can tell you: reviews that mention tearing are worth more than the marketing copy above them, and weight per bag is a rough clue only when you compare bags of the same size and shape. Our listings carry the flat size, the count and the material.
HOUT Easy-Open Dog Poop Bags, 120 count
Black PE bags, 8.7 × 11.8 in flat, with a mouth designed to separate one-handed. Also available as a 360-count bulk pack.
Size and the opening
Bag dimensions are quoted flat, which makes them sound roomier than they are. What matters is whether you can get your hand inside, pick up, invert and tie without touching anything. Ours are 8.7 × 11.8 inches flat (220 × 300 mm), measured over the whole bag including the seams; compare that against your current bag rather than treating it as a rule.
The opening is the part people actually complain about. Separating the mouth of a bag while holding a leash is the common frustration, and rolls that tear diagonally instead of at the perforation make it worse. Opening ease also changes with cold, gloves and dry hands, so if you walk through hard winters, try a small pack in those conditions before committing to a bulk pack.
What the environmental labels actually mean
Three words get used as if they were interchangeable, and the differences are where the confusion lives.
- Plant-based refers to the feedstock, sometimes only part of it. It does not by itself mean the bag biodegrades; plant-derived PE behaves like conventional PE.
- Compostable is easiest to judge when the claim names its standard, certifier and conditions. Many common certifications apply to managed commercial composting, which is a different environment from a backyard pile or a landfill.
- Biodegradable with no standard or timeframe attached tells you very little on its own.
The FTC's Green Guides give specific guidance here: an unqualified degradable claim should be backed by evidence that the entire product completely breaks down and returns to nature within one year after customary disposal, and such claims generally should not be made for items that are customarily landfilled, incinerated or recycled. Modern landfills are also built to limit air and moisture, so a compostable bag sent to landfill is not in the conditions its certification describes.
About ours: they are conventional PE. We do not market or certify them as biodegradable or compostable. If a certified compostable bag is what you want, check which standard it is certified to and whether your area actually has a dog-waste composting program to send it to.
Where ours fit
We make the Easy-Open bags in 120 count, the 360-count bulk pack, and a SYNC Poop Bag Pouch in soft fabric that clips to a harness, leash or bag. The soft body can flex when the end of the roll pulls at an angle; before buying any dispenser, ours included, check that your roll diameter fits and that you can work it one-handed.

Two habits worth keeping regardless of brand: wash your hands after walks, because the outside of a bag can pick up contamination and small tears happen, and put bagged waste in general trash, never the toilet, unless your municipality has a specific rule for pet waste.
Quick questions
Are your bags biodegradable? No. They are conventional PE, and the listing says so.
Can I see what is inside? Not easily: they are black with a green logo. If you are keeping an eye on your dog's digestion, look before you bag, and talk to your vet about anything that worries you.
Will they fit my dispenser? They come as rolls in the common roll format, and the SYNC pouch takes them as-is. For other cases, check the roll diameter your case accepts.
If the opening and the size sound right for you, the 120-count pack is the low-risk way to test them against your routine; if they earn their place, the 360-count pack works out slightly cheaper per bag. Sorting out the rest of your walk gear? We have also written about choosing a harness.
