Lawn problems

Dog urine spots on a lawn

Concentrated nitrogen in urine can burn the center of a patch while a more diluted edge may grow greener.

Typical pattern

A small dry center with a lush green edge can result from different nitrogen concentrations.

Fresh spot

Prompt dilution with water may reduce the local concentration in soil.

Repeated route

Patches clustered near one exit or post point to the dog's routine.

More useful detail

How to narrow down the cause

Do not repair with fertilizer

Adding more nitrogen can enlarge the damaged center.

Create a resilient area

A washable surface or designated spot can be more practical than repeatedly repairing turf.

Problem

What to do step by step

  1. 1

    Dilute a fresh spot thoroughly with water when you can act promptly.

  2. 2

    After dead grass loosens, prepare the surface and reseed during suitable growing conditions.

  3. 3

    Encourage the dog to use a designated area that is easier to maintain.

Observation

What to watch next

  • New spots appear less often on the main lawn.
  • Reseeding fills damaged areas.
  • The dog's diet has not been altered without veterinary advice.
Important

Do not give a pet urine-altering supplements without veterinary advice.
