Thanks! I just looked up something on the web about 48 hours after watering. Sounds about like what was said in the last post (Patti). I have a small neighborhood park across the street. We have been going there for the last couple of hours. What a pain! Then I asked the neighbor next door if we could use their lawn in the middle of the night...no problem. I told them I bet they had never been asked permission for a dog to "go" on their lawn before! It is not wise to be wandering in the park after dark, even though it is a good neighborhood.
