How can I repair yellow grass stains from pet urine?

That’s female urine and the best I could do was to water the heck out of it, to dilute it.

The grass will grow back if you pull out the dead grass, selectively.

The only solution is to rake out the dead yellow grass, water well, add soil and grass seed and water daily until it sprouts. It is a never ending job unless you can train your dogs to go in an area that doesn't matter. It doesn't matter if you have a male or female dog-you will get urine spots from both.

Restoring grass to bare spots on your lawn caused by dog urine, piles of leaves or objects remaining on the grass too long can best be accomplished by overseeding. Here are a few steps to ensure the best results for your efforts.

Start by raking away the leaves, dead grass or thatch to expose bare soil wherever the turf has completely died. Grass seeds need to be in contact with earth before they will grow.

Overseed the spots with grass seed and rake lightly to put the seed in direct contact with the soil.

Apply more soil on top. Spreading it out until it is about 1/4-inch thick.

Give the newly-seed area a good watering with a sprinkler and continue watering daily until the new grass is established.
