Query: Best eco friendly weed killer

We have dogs and are concerned not only for their safety but for the earth as well. Toxic weed killer just isn’t an option so we wanted to give this product a try. We have a large brick patio that weeds pop up. I sprayed this product on them and the instantly started turning brown. I came home today and am happy to say all of the weeds are brown. I was able to let the dogs out tonight without worrying! Love that this is a small company as well! We will for sure use this product again. Oh and it smells awesome!
