Wouldn’t grubs already have caused damage to the roots and exited by August? You may want to apply a preventative treatment around June.
Eggs hatch in late June to July, and that’s when preventatives work. Grubs feed and burrow for winter, then pupate in late spring/early summer. They can emerge as beetles and lay more eggs. Some grubs can indeed live as grubs for two years, leading to multiple generations. Preventatives target most of them.

I didn’t know grubs stayed in the ground that long before turning into beetles. Thanks for the explanation.

Interesting. I don’t know much about grubs other than what I’ve read online.
@Niko
I expanded on my previous answer if you’re curious. Check for grubs again; dig deeper, down to about 2 inches. I really suspect grubs more than dog urine here. The second likely suspect is a weedy grass like poa trivialis that could be dying out.
@Dakota
I’ll check again; thanks!

They mentioned it happens every summer. Wouldn’t grub damage be permanent? Am I wrong?

Many grasses can repair themselves through rhizomes.

Could this be burning due to excess nitrogen in these areas?
Stick a pitchfork down to see what you hit (ensure utilities aren’t buried). Bet you’ll find rocks and debris. I had this in my new house, found gravel, rocks, and even bricks down a few inches. I dug it out, added fresh topsoil, and reseeded in the fall. It’s been fine since.
