Picking up after your dog isn't exactly the most enjoyable chore. Let's face it — it's gross! It can be tempting to skip this task, but doing so is not only bad for the environment and public health — in many places, it's also illegal. Keep reading for all of the reasons you really do need to pick up your dog's poop, and read on to learn how to clean dog poop from grass.
Why Picking Up After Your Dog Matters
It May Be Required by Law

Many communities and municipalities require cleaning up after your dog. While this might be obvious in parks and public spaces with posted signs telling you to clean up after your pup, it's not uncommon for neighborhood homeowners associations and neighborhood covenants to require picking up poo even in your own yard. Even if you live in an area without posted signs or a homeowners association enforcing the rules, your city or county might have laws and regulations in place requiring you to clean up after your pet in public spaces.
Dog Poop Is Not Fertilizer
People often believe that leaving dog waste to decompose in the yard is good for the lawn, but the truth is that dog poop is toxic for your grass, said PetHelpful. Unlike cow manure, which is basically composted grass, a typical dog's poop, which is made acidic through natural digestive processes and their microbiome, is enough to destroy the grass underneath it. For this reason, dog poop also shouldn't be placed in your compost or used to fertilize your garden. In either case, it contains bacteria that could contaminate your vegetables.
It's an Environmental Pollutant
In fact, the Environmental Protection Agency describes dog waste as containing two types of pollutants: nutrients and pathogens. Dog waste that gets washed into waterways may carry pathogens that affect living things in the water and can make people sick that are in contact. Also, nutrients released from dog poop can stimulate the growth of algae and other plant life, making the water unsuitable for recreational uses.
It Carries Diseases
Even if your dog doesn't show any symptoms of illness, their waste could still carry bacteria and parasites that are harmful to other pets and humans. And you don't need to come into direct contact with dog poop in order to contract an illness from it — diseases in poop can be transmitted by flies or other pets that come into contact with it, said iHeartDogs. Here, according to PetHelpful, are some of the illnesses and infectious organisms carried in dog poo:
- Roundworms
- Salmonella
- E. coli
- Giardia
- Leptospira
- Parvo virus
- Coliform bacteria
It Can Overwhelm the Ecosystem
While you may think your own dog's poop can't do that much harm, keep in mind that your dog is likely one of hundreds in your area. iHeartDogs pointed out that while the ecosystem can generally handle up to two dogs per square mile, in urban areas, there are on average 125 dogs per square mile — far more than enough to overwhelm the local ecosystem with their waste. By picking up after your dog, you'll help protect the ecosystem.
