OK, I have two dogs, a masculine and a female. They own turned large patch of the grass yellow(dead) as well as worn out a patch from playing and running on it so much. The worn out patch very soon looks like rreally short limp grass , with mostly dirt perceptible. How do I fix these patches beside little to no chemicals and with minimal action as I have a immature baby and don't enjoy too much free time. Thanks.
Answers:    Try to keep your dogs sour this area for a while, after get a big bag of peat moss. Very inexpensive and glib to carry. Pour over the nouns and start to water regularly. The peat moss will nurture the soil and grass will grow back athletic. We did this and it worked with little work on our chunk. Or you could try taking out the grass in that nouns and putting down pea gravel or mulch or ivy, make it look close to a landscaped nouns or bed.
Move the dogs into another fenced-in run, to give this motionless grass a chance to revive itslef. My friend have the same problem, & she poured Mulch adjectives over her yard.
