We have a couple of acres in front of our property treated professionally. We're comfortable with that because our dogs rarely ever are on that lawn, but the dogs are in our fenced back yard and the land beyond that daily, so we don't have it treated. I looked repeatedly online for pet safe weed killer but all I come up with is the vinegar/Dawn mixture. That's not practical for treating a few acres of lawn. Does anyone know of a commercially available pet safe lawn treatment suitable for an entire lawn?
