Why is dog poop in the lawn dangerous?

“As a licensed Veterinarian, I'd be happy to offer my insights on the potential dangers of dog poop when it comes to mowing lawns. Mowing over dog poop does pose potential risks to both humans and other animals.” --Michael Thompson Founder & Leading Veterinarian Pets Food Safety

Mr. Thompson went further and gave the following three examples of how dog poop can be harmful to people, pets, and the environment itself.

1. Dog Poop Transmits Parasites and Diseases:

It’s no secret; dog poop can contain many types of parasites. These can include:

  • Roundworms

  • Tapeworms

  • Campylobacteriosis, 

  • E. coli

  • Gladaria, 

  • Parvo, 

  • Salmonella, 

  • and Cocciola. 

The worst part is that these parasites can be spread to humans and other animals with just simple contact with contaminated surfaces. And when you hit a pile of dog poop with lawn mower blades and sling it across the lawn, you are risking spreading parasites everywhere. Which your dog can easily pick up from eating grass

Talk about GROSS!!!

As you can see, improperly disposing of dog poop won’t just ruin your lawn, it can cause health issues too.

2. Dog Poop Contaminates Waterways

Look, when dog poop is in neat clumps on the lawn, it may not be the prettiest sight, but it is much easier to clean up. 

Here’s the deal, mowing over dog poop breaks it into smaller particles, and that's NOT A GOOD THING. These particles can spread throughout the lawn. Then when it rains, these particles can wash into local waterways, where they can contaminate local streams where animals drink

Or even wind up in drinking water!

WORST OF ALL, many of these particles may not get removed by the filtration systems and can wind up contaminating water intended for human consumption. 

While animal waste is a part of nature. When it comes to suburbs and big cities. There is simply such a high concentration of dogs that it can really start to add up. And the harmful agents like e coli that are contained in dog poop can begin to cause issues on a larger scale.

3. Soil and Plant Health Issues

“Dog feces contain high levels of nitrogen and phosphorus, which can cause "burn spots" on your lawn when left in concentrated amounts. Mowing over dog poop can distribute these nutrients unevenly, potentially damaging your grass and creating an unhealthy lawn environment.” -Hanif Roslen, Founder of

Look, this is an important point.

While a little dog poop may actually benefit the lawn. It doesn’t take long for it to cause issues. The build-up of nitrogen and phosphorus can cause brown patches in your lawn. Just like dog pee can.

One great way to handle this issue is to make a designated potty spot where your dog can use the restroom and not damage the rest of the lawn. Here are more great ways to make your lawn more pet friendly
