Pattern clue: dead center + darker green ring30-second field check
No single visual clue proves the cause. Use location, pattern, plant symptoms, timing, and site history together.
Do the spots match the places and route your dog regularly uses?
Are there several small circles rather than one expanding or irrigation-shaped area?
Does a straw-colored center have darker green growth around the edge?
Are leaves dry without lesions, matting, water-soaked tissue, or visible fungal growth?
Did the pattern follow repeated visits rather than a weather or irrigation change?
If the clues conflict, can local extension review whole-pattern and close leaf photos?
The repair fork
Dilute a fresh deposit promptly with plain water. Protect living turf from another concentrated deposit. Clear and repair fully dead turf with material matched to the grass and season.
