I have a neighbor who moved in next door. she owns a dog, it’s a female, now form what I know, female dog urine is more acidic than a male dog and it leaves behind browen spots on our grass which means my grass is burned by the dog’s urine and there the grass is killed. Some folks take care of the grass and keep it healthy looking. But they don’t like the look of having brown spots on their grass because someone next door does’nt know how to pull their dog’s leash to have them urinate some other place.
