I have a shepherd and a rottweiler in a medium size yard and this stuff is the best, hands down. Too bad none of the stores areound me carry it. Well worth the online shopping and shipping. Makes the yard smell like a pine forest

I have used this in my covered dog run, as well as the yard, and its great! I have a small home based pet sitting business, and don't want to annoy my neighbors with the smell of urine. This is a must have tool during the hot summer months.
