Please tell me the names of lawn weed killing products that are pet friendly.
Thanks for writing. It depends on what type of lawn weeds you have. If they're annual weeds, like crabgrass, then you can use a product containing corn gluten. You need to use it early in the season --- like around the time the forsythia blooms --- to stop those annual weed seeds from sprouting.
If they're perennial weeds though, there aren't any great pet-safe options. That said, if you maintain a healthy lawn (letting it grow at least 2 inches tall, watering it in drought, feeding it regularly, and aerating yearly), it will do a pretty good job of controlling perennial weeds on its own.
