How long does it usually take to dry till it's safe around pets?

They say yes in public but call them and ask, they’ll say “the treated grass is only safe for consumption 12 weeks after it dries” but dogs eat grass

Thank you for your question. We are unable to provide a drying time as there are too many variables to consider. Please allow a few hours to dry and check for dryness prior to allowing pets back on the treated area.
