Thought it was a great idea at the time to get fake grass, I've got a bull mastif which tore the garden up all the time, so decided on fake grass.
All comes with drainage holes etc, (thinking it'll be good enough etc) we've had it down about 2 years and where he's pee'd all around, the smell kicks up something fierce when the sun beats down on it, we've tried just about everything on the grass to get rid of the smell but to no avail (wee crystallize's/sticks on the plastic) Unless someone has the solution for the smell, in my honest opinion I would definitely stick to the real stuff.
