Brown Spots

[dclark2037]

in my own bermuda lawn. These are very small brown spots, maybe 2" total but moving all around my lawn. My lawn is IMO in great shape with the execption of the spots. I have recently fertilized with Andersons 24-5-11 w/3% iron. but these spots were already here. Any ideas and possible cures?
Thanks David

Moving????

Do you have a pet that may be damaging the lawn?
(Concentrated pet waste can act as an "overkill" fertilizer).
