I have 3 large dogs in a backyard. They wrestle non stop and have literally either trodden down every blade of grass, dug it up or, in the case of shrubbery, chewed it up. The only thing remaining is an enormous old black walnut tree. So, not only have they completely torn up the yard, it's shady too. We need to do something to hardscape the backyard without breaking the bank. Part of the yard will have wood decking, other parts will be patio pavers. I was thinking of trying something like astroturf for the remaining areas. thoughts?
