All lawn foods are safe for dogs when applied as directed. You’ll want to keep the dogs off the lawn for a few days if you apply a weed killer (like a weed & feed or weed killer spray). Once the weed killer has been washed into the soil by rain or watering then the dogs can go back onto the lawn. Dogs should also be kept off the lawn after insecticide applications…all of this is outlined on the packaging of the product so read and understand that before using. If you want to choose an organic lawn food, we carry the best…Espoma. Again…plain lawn food without additives like weed killer are perfectly save for dogs when applied according to the direction on the package..
