What’s wrong with this lawn?

My son’s lawn has developed many areas where the grass is struggling to stay growing – or, maybe it’s more that the ground won’t support the growth of grass. He has noticed that the lawn felt lumpy when he mowed and when he checked the spots, there is no grass growing over these areas but, rather the grass has laid over the area and makes it look like there is grass there. When he trims that grass, there is actually a bare area underneath. He does have a male neutered dog that does his dirty business and urinate all over the lawn and sometimes the waste will sit on the lawn for a week or so. Could either be the problem? He doesn’t see evidence of grubs or other insects. Help.
