We love everything about these simply named Poop Bags. They are made in the United States of plant matter including corn, vegetable oils, and compostable polymers, and they meet the ASTM D6400 standard for commercial compostability.

There are several versions including convenient rolls that fit standard holders that attach to leashes or your pocket when you go on walks. There are long boxes you can keep near the back door where you can take a bag or two at a time, and there are bags with easy-to-tie handles.

If you purchase bags from the company’s "You Buy; We Donate" line, a portion of sales are donated to support nature-related charities. Funds have helped plant trees, protect sea turtles, sponsor marine research, and support the Jane Goodall Institute.

Our testers like that these bags are soft, easy to separate, and that they feel durable. They are sturdy enough that they don’t feel like they are going to tear and they are roomy enough that they can tie easily. There’s no smell, and they liked the feel-good aspect of contributing to animal causes. It made paying a little extra worth it.

Tester Insight:
“They feel a little thin when you first hold them but don’t feel thin when you use them. They don’t feel like you’re touching poop through them.”

Best Large Bags

Doggy Do Good Biodegradable Poop Bags

A close runner-up, Doggy Do Good bags are vegetable-based, made primarily from GMO-free cornstarch and other bio-based components. The company says the bags break down in just 90 days. They are certified compostable (ASTM D6400) in the United States and in Europe (EN 13432) by TÜV AUSTRIA, an international certification body.

They’re available on small rolls for dispensers, on large rolls, and with or without handles. They are thick and supposedly leak-proof, although we didn't test this. The side panels are gusseted, so the bags expand for extra space. The capacity is 2.5 quarts or a half gallon.

The company has pledged to donate at least 10% of profits to animal rescues and no-kill shelters, including the Humane Society of the United States, Best Friends Animal Society, and the Animal Welfare Institute. The core and packaging are also made from 100 percent recycled materials.

Our testers found these very easy to get open. The baggies are soft and don’t stick together, and they expanded, so there’s plenty of room for large loads. That also made them very easy to tie and easy to carry.

Tester Insight:
“These were longer and wider, which made it much easier to get my hand inside, pick up the ‘presents,’ and pull it back over to secure and tie."

BioBag Standard Pet Waste Bags

BioBags are made from a resin derived from plants, vegetable oils, and compostable oils. The resin is sourced from Italy. The bags meet the ASTM D6400 standard.

These compostable bags come in standard and large sizes in a hangable stack where you can rip off one at a time. They also come in a roll for easy portability on walks, and there’s a version with handles if you don’t want to struggle with tying them. 

Except for the bags with handles, these bags are black and very soft, and flexible. There’s no scent, and they are easy to separate. The bags are a little smaller than some of the others we tried. Testers with larger dogs had trouble tying the bags once they were full. Some testers, however, really liked the look of the black bags.

Tester Insight:
“These were fine for my smaller dog. The bags were narrower and shorter, so I would not use for my large dog.”
