We are struggling with keeping our grass alive with a 3 year old 140LBS Great Dane and 4 month old GSD. They donít spend too much time in the backyard but that doesnít stop them from turning that time into race time. We have a pretty small yard and I have already tore out half of the grass and put in Cedars Hog Fuel, thatís has done wonders with keeping the mud down. They have however found other ways to track mud in, like running on the grass enough that it is starting to turn to mudÖ.. Well I donít want my whole backyard to be the Cedar Hogs Fuel so I have been looking for grass or grass alternatives that could hold up against my two monsters. My friend has told me about RTF Grass and that it is a hybrid for shaded areas and high traffic. Has anyone used this RTF grass or found a type of grass that would hold up to my two dogs?
