How Dog Poop Affects Your Lawn (And How to Fix It)

May 12

If you’ve noticed yellow patches, dead spots, or thinning grass in your yard, your dog’s poop might be the culprit. Here’s how pet waste silently wrecks your lawn — and how to prevent it.

1. It Burns the Grass

Dog waste is highly acidic. When left to sit, it overwhelms your lawn’s pH balance, causing yellow or brown burn marks. Unlike cow manure, it’s not a fertilizer — it’s a toxin to your turf.

2. It Blocks Sunlight and Moisture

When poop piles sit in one spot too long, they suffocate the grass beneath them. The lawn can’t get sun or air, leading to thin, patchy spots.

3. It Encourages Fungal Growth and Disease

Pet waste introduces bacteria and can lead to fungus or mold in your soil. That weakens root systems and invites pests — especially if your lawn stays damp.

4. It’s Hard to Reverse

Once the damage is done, fixing it can require reseeding, soil treatment, or full patch replacement. Prevention is easier (and cheaper) than recovery.
