Question
I live in Henderson, Colorado which is about 25 miles northeast of Denver and my zip code is 80640.  I own a female german shepard and in my back yard I get brown/yellowish spots where she urinates.  My grass type is Kentucky Bluegrass.  The grass pretty much looks dead.  How can I stop this from happening?  
Thanks for your help!

Answer
two options:
- you can flush the root zone with plenty of water everytime you notice the dog doing it's business. once the spots turn brown it is too late. you need to do this as soon as the damage is done
- train the dog to go in a designated spot in the yard and not on the lawn. aware this is not easy by any stretch of the imagination, but unfortunately it is one of the better choices you have.

there really is nothing you can do, once damage show up. the high salt contents of the urine kills the grass plants. Below, I have given you a link to an article on the subject. Copy/paste the entire line into your browser's address/location bar.

Note: do not listen to advise such as gypsum (not practical) and giving dog special diets (can be dangerous for it's health). A diet is not going to change the salt content of the urine (contrary to popular belief). You need to get the dog off the lawn, or the urine flushed through the root zone.

I am aware that this was probably not what you hoped to hear, but from many years of dealing with this issue, it is as it is ...

(if you want to hear some different advice, then spread gypsom on the lawn and feed the dog tomato sauce. it won't help, but it apparently makes a lot of people feel better about it !!)

Have fun
