The Best Biodegradable Dog Poop Bags

Cleaning up after your dog is possibly the one downside of owning one. It’s just a fact of being a dog parent that everyone has to deal with because nobody likes the risk of potentially stepping into dog poop. 

Picking up dog poop is really easy. You put your hand into the bag, scoop up the poop, tie the bag, then throw it away.

Thing is, not all dog poop bags are good for the environment, because a lot of them are made of plastic. Sure, you can still throw it away, but the bag will cause more harm than good to the environment. 

So, you might think that biodegradable dog poop bags are the way to go. This is partly right, but not all biodegradable dog poop bags are as good as they say they are.

It’s all pretty complicated, which is why we have created the ultimate guide to eco-friendly pet waste management! Here are the best biodegradable dog poop bags. 

Pros And Cons To Biodegradable Dog Poop Bags

The problem with dog poop bags that are marketed as biodegradable is the risk of greenwashing. Greenwashing is a term used to describe marketing spins that make a product seem more eco-friendly than it actually is. 

This means that while you might assume your biodegradable dog poop bags from the pet store will degrade within a few months, this isn’t always the case. These bags aren’t designed to degrade quickly in the trash or compost, instead, they can take several years to degrade.

This is because the landfills the bags go to aren’t designed to encourage biodegradable objects to degrade, as these organic materials require heat, compression, and air to break down. Without heat, compression, and air, these “biodegradable” bags simply rot and produce methane. 

This doesn’t mean you give up on biodegradable dog poop bags entirely, because the traditional plastic poop bags break into catastrophic microplastics which are far worse for the environment. 

You’ve also got to keep in mind that biodegradable doesn’t always mean compostable. Biodegradable bags will degrade naturally in a landfill over a longer period of time than compostable bags that will degrade in a compost over a few months. 

Biodegradable Dog Poop Bag Alternatives 

So, you can’t exactly throw away a biodegradable dog poop bag in the trash if it’ll just go to a landfill where it won’t degrade. Luckily, there are some alternatives and ways to promote the degradation of the poop bags. 


While you might assume you can just chuck the biodegradable dog poop bags into your regular compost, this isn’t actually a good idea. Unless you don’t have any edible plants growing in your garden, the compost (and therefore the unhygienic dog poop) will be used on vegetables and fruits that you could potentially eat. 

However, there are some composters available that are designed specifically to break down dog waste. These composters are dug into the ground, and then you simply add the waste along with some water to promote the breakdown process. 

We recommend this Doggie Dooley Dog Waste Disposable System for your own mini septic tank!

Bury The Poop

This isn’t the best method for those with a small backyard, but if you have a large outdoor space that can be home to a small area designated to bury biodegradable dog poop bags, then you can simply bury the poop.

Just make sure to bury the waste at least 5” underground and to keep it away from edible plants, vegetables, and water sources!

To Flush Or To Not Flush

It is not recommended to flush dog poop in the same way that you can flush human poop. This is because not all sewage systems can handle the breakdown of dog poop, not to mention the potential parasites found in dog poop that can be detrimental to the safety of the water and marine wildlife. 

Best Biodegradable Dog Poop Bags

If you have no choice but to use biodegradable dog poop bags when walking your dog, don’t worry! Biodegradable dog poops are far better than using traditional plastic bags, so don’t beat yourself up too much if you can’t make your own compost system in your backyard. Not everyone has the space to do that, after all. 

The key is to find dog poop bags that meet ASTM D6400 standards, which is the recommended compost criteria that means the biodegradable bags will actually break down. 

Here are the best biodegradable dog poop bags!
