| Hi all -
Could use help identifying brown spots in lawn. There are several scattered throughout the yard, but they are clearly distinct from one another. I would like to treat, but don't know if it is fungus or insect. I don't see signs of grubs. I suspect it's not grubs as this seems to be a very acute patch turning brown - as if it were burned dry, but it's not stressed for water. Lawn is mix of P. Rye, fescue, and KBG. Hopefully pics speak 1,000 words. Many thanks!

| Neighbors dog peeing on your lawn? Overfilled lawn mower and some gas spilled out? Chemical spill? |

| Is there poor air circulation or bad drainage there? How fast did they appear? Has it been really hot there? |

| looks like dog urine to me as well |

| Yup, some dog did the deed. All you can do is try to give the area more water than usual and hope the dog visits right after or just before a rain. |

| Yes the picture speaks 1,000 words. Another vote for dog pee. When did you fertilize last and with what? Water frequency and time? Otherwise the color, density, and mowing height look pretty good. |

| Okay - I forgot to mention that we do have a small dog. :) Before you all laugh at why I didn't mention that: 1) this didn't happen last year (when we first got the dog) and 2) there are only a few spots scattered throughout the lawn. That is - he pees multiple times a day everyday - why wouldn't the whole area be decimated by now? I will also add that I haven't fertilized in a while - planning to give it a shot soon. Will this help pee spots or make worse? Many thanks |

| This is a bad time of year to fertilize cool season grass. If it was the dog, it would likely make the spots worse. Have you considered the possibility of Dollar Spot? I really can't tell from the picture - just something to consider. Honestly, if it was me, I would spot treat for it anyways - it shouldn't be very expensive for spot treatment. Again, a solid diagnosis would be beneficial before buying fungicide. |

| I have 2 dogs and trained them to go in a natural wooded area of my yard. once temps are above 75 their pee will burn my grass everytime. late fall through early spring there is no problem. female dogs are the worst. |

| Usually female dogs cause the problem because they pee all in one spot. Not as many males do that. More fertile soils handle this better. One thing you could do is the scatter a handful of table sugar on the spots. Sugar feeds the bacteria and causes them to repopulate. When you have enough of them, the urine will not have any impact. |
