How can a dog urine affect my lawn?

Dogs are of course known to be man’s best friend; however, dog urine can cause damage to your lawn.

How can a dog’s urine affect my lawn?


The high level of urea present in a dog’s urine is the reason for scorched patches appearing on the lawn.

Urea is a compound of nitrogen, and while nitrogen is essential in allowing for strong grass growth and good colour, a high concentration will have the opposite effect, and cause the grass to turn yellow or brown. In many instances, the area of infected grass is surrounded by an exceptionally lush, green ring of growth, which occurs as the level of nitrogen is reduced and has the same effect as when applying nitrogen in fertiliser.

How can you prevent damage to your lawn?


While the level of urea in a female dog’s urine is slightly higher than that of a male, the chemical composition of the urine doesn’t differ that much.

You can consider applying water, immediately after the dog has urinated, which can help to dilute the urea, but generally, it’s difficult to prevent damage to the grass.

The most efficient repairs can be achieved through either the removal of the damaged grasses or worst-case scenario the surface layer of the lawn, which is then backfilled with a top dressing, firmed and over sown, with a full recovery within 4-6 weeks.
