I guarantee you guys, this artificial grass is really strong. I bought a portion of this cashmere 4o for my dog's potty training which he like. But before he get used to it, my dog scratched and gnawed the blades of the artificial grass really hard and I'm surprised that it didn't tear. I just hoped that this artificial grass will last long considering my dog is a hard digger. But as I can see how it was stitched, I believe that it will last longer than what I am expecting.
