Urine, whether a male or female dog, or human for that matter, will tend to kill grass, yes.
You cant. Only female dogs do it and there is no way to prevent it.
You can buy a product called Dog Rocks and put it in your dogs bowl. It helps neutralize the acid content in the dogs urine and the spots in the grass should stop being so noticable.

Burn it
In the grass
Dogs eat grass to help digest their food.
This is because of the scidity of the dogs urine. The type of grass you have can not tolerate that much acid and the roots are probably dying. The best thing to do is spray water onto the spot, right after your dog urinates. This will dilute the acid and hopefully save your grass.
No. Some female dogs frequently urinate in the same spot all the time. Vinegar will not keep her urine from killing a spot in the grass.
Dogs roll in certain parts of grass to mask their scent with the smell of the grass or to mark their territory with their own scent.
Dogs perceive grass as shades of yellow and blue due to their limited color vision.
yes
In green grass, water is present, and this prevents it from burning.
