I apologize in advance because I'm sure this is a duplicate post, I've searched the forum, but can't find exactly what I'm looking for, so with that said, here goes. I just moved into my first home two weeks ago, the previous owners did an exceptional job on the yard and garden, in my opinion. I have two Boxers and despite my best efforts they have both(we have a male and a female) urinated on the lawn before I could get them to their dog run, where they are supposed to go. Anyway, I live in Utah, and to be totally honest, I'm not sure what type of grass I have, but the spots where the dogs urinated is totally dead. Is there any hope, what can I do? The area right where they urinated is yellow and in some places, there is a dark green ring outside of that where the lawn looks to actually be growing stronger, I don't get it. Is there a fertilizer or a treatment of some kind I can do to save or regrow these areas? Any help would be sincerely appreciated.

Jenniferrose--Some recent research has shown that the "winterizer" approach to fertilizing isn't actually the best thing to help roots. Instead, the best thing is to give the grass 1 lb of actual N per 1000 sq ft of lawn after the grass has stopped growing but whilt it is still green. What happens is that the grass is still actively photosynthesizing, but it puts all of its effort into storing the energy in its roots.

Dlarsen--You should probably start a new topic with your questions. Also, it would help to know approximately where in Utah you live. We don't necessarily need to know exactly, but conditions along the Wasatch front are very different from the "Dixie" part around St George.
