The SYNLawn Pet System is terrific for dogs. It eliminates all the mess. It keeps all the mud, fleas, ticks, grass clippings, etc from coming into your house. The dogs will not dig because we have eliminated from below the turf the bugs and grubs they hear. We use a deodorizer in the top of the grass that eliminates a lot of the ammonia smell from the dog urine.
