Advise needed to recover these lawn

[tnylmzr]

Good day everyone!

I have a small garden and I have lack of information&experience about maintaining it as beautiful as it was before. I share the last view of my lawn in attach file. Other parts besides the photos are pretty green enough.

Info: I haven't fertilized the lawn since April and in my country we are getting into Autumn now.

If you have any advice I'd really appreciate. Thank you in advance!
Cheers

I see no one else has replied so I will. IMO you have multiple problems. The first is compaction, the second is lack of nutrition, the third is possible grub damage and the fourth is from a dog urinating on the grass, that is if you have a dog. I would aerate the entire lawn first and second I would fertilize. It is too late to do anything about grubs as they have stopped feeding by now. And if you have a dog pour a mix of molasses over the yellow areas. And keep the grass mowed.

Maybe there are some problems with soil it lays on?
