We also have a problem with this, although it used to be much worse. I have looked into giving Koby supplements to help with the urine ph level, but there are reports of the supplements actually causing harm to dogs so I chose not to treat Koby but instead treat the lawn. In the spring/summer I soak the pee area with water daily, he only really goes in one area, so I make sure to saturate the lawn with water to dilute the urine and it works really well. We have a small spot of grass that's not growing back in so well but our lawn is looking much better this year than it has in the past. Hopefully this helps a bit, good luck and welcome to BPO!
