when I planted my grass this year it came up beautifully. now it is starting to fail. you can pull it out easily, the roots dont seem to be very deep. also, the blades of grass dont seem to be maturing, still very thin or frail. any suggestions?
on a side note, is there anything that can be done about pet urine killing my grass in spots other than getting rid of the pet?
I should note that I loosened the soil to about 2 inches, used weed and feed or yard starter, and kept the soil at least damp for 10 days.
I live in Kansas, the eastern part.

Have you feed your grass with a fertilizer ( forgot to do that did you ) go to a garden centre and get an approved fertilizer use it and remeber to use it next year

well, when the grass first is planted, you need to water lightly at least once per day. Once it sprouts and is growing, then you cut it back to every other day. As it grows more, you want to water it more deeply (for a longer period of time) once a week. This will encourage deeper root growth. If you are watering lightly, the roots don't have to go very far to get water. What you do when you water more deeply and less frequently is force the roots to bury more deeply in search of water. It'll make for sturdier grass plants. Also, 6 weeks after planting, you will want to fertilize again (I assume you used a starter fertilizer when you planted initially). My front yard is 6 weeks old this weekend in fact, so I'm about ready to fertilize it too! As for the dog, I would move him/her to a spot without grass, or take it for walks to do its business.
