I have very strong and active young pit bull. He like to play in the back yard. Problem is... he pees on one spot and grass dies and turns into big brown spot on the grass and it really looks ugly. I tried sodding the area but he dig it out, I seeded but it wouldn't grow. I tried artificial turf patch but he pulled it up... basically I was giving up. About two weeks ago, I was going though homedepot website and found this product. It said you will see green all the time, just install on top of the problem area and it should fix the problem. It sounded good so ordered it. It came about 2 days. It had instruction on how to install along with u shaped pins and seeds which I didn't really need. It took me about 1/2 hr to install. At first I thought I did bad installation because it was puffed up. But later I found out that it eventually goes down to blend in with natural grass. It's been two weeks and the natural grass and the pet turf blended well and now it's hard to tell I even installed it. In the beginning, My dog tried to bite and pull on it but now it's settled in so he doesn't even bother. Overall I'm happy with the product. Anyone who has dog that has back yard... should have it. I wish it was little bigger.
