Review title is Not for us [SEP] This product did not work for me at all.  I think in order for it to work I would have needed several bottles for our small grass area.We live in AZ and we have artificial grass with two 50 lb dogs. I read all the reviews on about 10 different products. I have used the granular stuff you sprinkle and 4 different brands of spray. As soon as the temp hits 90, with the sun directly on the grass, the smell begins. When the sun sets the smell is gone. I have just accepted I have to spray it every day early in the morning, during the summer. People need to realize that the smell keeps coming back because the dogs keep going pee. To use it once and say it does not work would be like saying you only have to flush once.
